Did you confirm that the ISC was good with your multi meter?

I had a 2nd ISC go out this weekend and I'm unsure how to determine if it took out the ECU driver. Is there a test I can do on the ECU to determine whether coil pair A and B are still good? The car is idle surging even with the ISC unplugged, so I'm leaning toward the ECU is fried again...

Can you post a side angle picture of the FIC injectors showing the FIC logo and the scribed portion?

While I agree that replacing a head gasket "can" be a few hour job; while you've got it apart, why not replace other stuff. Front case, oil pump gears, BSEK, timing belt, tensioner, ARP head studs etc.Those few items will pretty much ensure that your car will run another 100k miles without...

Finally had time to remove the black ISC and see what it Ohm'd out at.Surprisingly, the entire thing was fried. Resistance was:Pin 1 & 2: 1.8 Ohms Pin 2 & 3: 0.4 Ohms Pin 4 & 5: 1.1 Ohms Pin 5 & 6: 1.0 OhmsNo coolant leaks anywhere near the ISC, so I've got no clue why it went out...

I replaced the ISC 2 years ago with the revised version because I was worried that the tan one would fry my ECU. Guess I'm sending the ECU to Tom/Dave to have it repaired.There were no coolant leaks at the TB that I'm aware of, but I'll crack everything open this weekend and see what I can...

Well, I figured out the problem. My ECU is fried. That explains the burning smell from 2 weeks ago when I went for an emissions inspection and the random hot start problems.From my searching, it looks like that's a blown ISC driver, which means my ISC is probably bad. Some days I hate...

I am running 91 UnleadedI was running ECMlink at the time and it was able to read the coolant tempThe FPS has been eliminated. The vacuum source for the FPR is coming off of the intake manifold.And how have you been? I rarely see you post.

Car starts great when the engine is cold. After the car warms up to operating temperature, if I shut it off, it will not restart unless I hold the accelerator to the floor. If I crank it for ~30 seconds with the accelerator to the floor it's hit and miss. Some of the time, it almost starts...

Best mod I ever did to the car. It felt great to throw the old hood prop in the corner of the garage.I've had em installed for about 6 months now, but have always wondered how strong they were...Figuring that the struts were barely enough to handle the weight of the hood. I was most...

Bit of an update. After 4 years, the car finally completed the emissions inspection. The last 2 times I tried, something happened. 1st time, the battery died after I shut the car off and the inspection place refused to test it since they would have to keep jumping it every time it was shut...

As long as your turbo fins look good, and if they don't need to be rebalanced, Justin on DSMtuners can do it...He does great work.

I forgot to mention. Knock sensor is brand new. I loosened it yesterday and it didn't make any difference. Will tighten it again and see if that helps.

Just got the new ECMlink cable and now am able to connect without issue (thanks again Yao). New problem is that I can max out the knock retard in every single gear at any engine speed. Even neutral, I can peg the knock counts by just revving the engine.Things I've tried: verified base timing...

Since nobody replied, I'm good to go anytime after July 20th.

Is the wire harness in good shape? Looking for the main harness that connects to the coolant neck.Or, if you're willing to sell just 1 connector, I'm looking for the connector that hooks to the AC cut-off switch. (The connector that hooks to the very top of the coolant neck)Also, how...

Was great meeting you as well. Thanks again for letting me hook up my ECU and DSMlink cable. Your car made me want to spend money.

Looking for a drivers side sun visor with no tears, rips etc.

It's not that the car actually fails, it's that anytime I've made it to the emissions testing place, something goes wrong. 1st time, the person who could do a VIN check had gone home sick for the day, so they told me to come back the next day. Went back the next day, got the VIN check, but my...

If you're going to replace it with the insurance money, there's a 91 still for sale in Longmont. click

If I can ever get this damn car to pass emissions, I'm in.

Does anyone in CO have a V3 DSMlink cable I can borrow for about 5 minutes? For some reason, my DSMlink stopped connecting the other day and I want to see if I have a bad cable.

What sort of work was done to the rebuilt throttle body?

Exhaust manifold heat shield and battery tie-down.

Ok. I'm an idiot. Once the guy (IIRC his name was Aaron?) told me I wouldn't be able to compress them by hand, I went ahead and installed em. Went on without much issue.Hardest part was getting them aligned so they wouldn't hit the fenders.

Does anyone have the instructions for these? I lost mine and can't get the strut to move. It's locked at full extension and won't budge.

If you're going to pull the balance shafts, it's much, much easier to pull the engine. I did the entire BSEK install with the engine in the car and it was a major PITA! With all the stuff I removed, I could have spent another hour and just pulled the engine. It would have saved me a lot of...

I've got 455/1000 in Colorado.

The GVR4 has been pretty uneventful so far - at least compared to my old 2G2G...OMG! 6 years and damn near $20,000 and the POS spun a bearing. Went through 3 mechanics, 2 engine builds, 1 engine fire, 3 turbos...All within 200 miles. After the 2G problems, I learned to never, ever pay a...

Always nice to see fellow CO people helping each other out. I think I need to have ya'll over to scream and yell at me to give me motivation to finish putting 455 back together.

Did you feed it unrestricted from the OFH? If so, I'd say that's the reason why you've got so much shaft play now.

I vote to do a nice cruise through the mountains in a snowstorm! Put that AWD and snow tires to work.

Quoting Racah15: edit: Dark Horse, I believe I have picked up some stuff from you before? I think we've met. I remember the screen name from the CODSM ForumsWe probably have. I used to have a 2G and I parted it out a couple years ago. So you may have driven up and bought some stuff from me.

Quoting Racah15: 6: Paint the car P26, Rally Red (Gorgeous color)I like everything on your list besides this step. Why not keep it the stock color?

Quoting mtbmafia: If you don't have a 2g I'd look at picking one up from someone for cheap.Running a 2G MAF requires modifying the intake pipe to make it fit. If you run an EVO8 MAF, it fits the stock intake pipe without any modification.Not to mention that the EVO8 MAF works better and...

Quoting hotrod: Where did you go to in CO? I spent almost 6 years at Buckley AFB in south Denver.Morrison, CO.

I drove my GVR4 back from San Antonio to CO in 2010.And you drove the G from WI to TX?

Are you the same 'Hotrod' who wrote most of the wikipedia page on E85?

Found one. Toybreaker to the rescue.

I'm looking for the drivers side timing tensioner mount bracket for a 6 bolt. It's the same one found here. clickPM with price.Thanks

As for the stock oil cooler. Apply some blue threadlock and tighten the stud/bolt to 30 ft/lbs (IIRC). That will stop it from backing off and dumping oil everywhere.I'd also suggest replacing the alternator with a Saturn alternator. Requires a bit of grinding on the alt its self, but the...

Since V3 supports speed density, in my opinion, there's no reason to run a GMAF anymore.

Quoting mitsuturbo: Have fun with the two 14mm bolts on the underside of the intake manifold.I found it easiest to drop the transfer case & downpipe to get to those 2 bolts. T-case & downpipe only take 10 minutes to remove. You'd spend 10 minutes trying to figure out another way to get at...

Is your BOV recirculated? It looks like it is in the 1st pic of the engine bay, and in the 2nd, it looks like you capped off the return line.

It's been quite a while since I updated this thread. And I'll even update with pictures later tonight.A month ago, I was driving the car on the highway and it overheated. I thought I had shut it down in time, but from that day on, anytime I drove the car, it would push coolant into the...

The more power you're putting down, the more stuff is going to break. If you need your car to be reliable, don't go crazy in a quest for horsepower.250WHP: DSMlink, injectors, Walbro 190, Exhauast/downpipe, intercooler, boost controller, clutch.

I'd either go with the EVO8 MAF, or ditch the MAF and run speed density. No reason to go the 2G or 3" GMAF route anymore IMO.
