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.
