Idled fine prior to cam and lifter install - nothing else changed. simply can not get the car to hold idle. BISS out all the way, tried adding/subtracting fuel on safc, even screwed in closed throttle position switch to see 10% throttle and it simply mugs down and dies. Keydiver chip set to 1000rpm idle.

Any ideas appreciated -

Colin

Are you setting the BISS properly per VFAQ?

well - if you back the thing out it will raise the idle, tighten it and you get the opposite effect. I HAVE IT BACKED OUT ALL THE WAY TO WHERE IT WILL STILL SEAL - this should result in a pretty high idle under normal circumstances. All fiac crap is gone.

Fact remains the thing idled fine and after cam install I can not get it to hold idle...

I think what he meant was, "Are you grounding the ignition timing plug and pin 10 on the diagnostic plug before you adjust the BISS?"

HOnestly- go back and reset following VFAQ- then start to rule things out- check timing again etc. Teh more you know is right, the less you'll have to look at /ubbthreads/images/graemlins/smile.gif

Is your cam timing right?

Are you sure?


Are you positive?

**Edit: One tooth off on the intake manifold will kill the idle, one tooth off on the exhaust and the car will run, but not well and you won't have power. If the crank is off by one, it may barely start if at all. that's been my experience with timing the 4g63 and being off.

I agree with prove it. It sounds like you did the timing belt job wrong.

lmfao - you all suck.

the timing is dead on. f*** a timing light - there is no cover. it takes .5 seconds to take off the crank pulley and

WAMMO!

Timing is dead on. I don't put timing belts on wrong. Especially on this dumpster chicken - there is nothing to it.

Everything is eliminated.


THE ONLY THING THAT I CHANGED WAS THE CAMS ,and now doesn't want to idle...


Why the F would changing to 264's affect the idle? People drop 272's w/o dealing with this...

You had to have changed something. Even 272's won't completely kill an idle. Going off like this only makes it harder for you to see a simple mistake when you make one. If you believe your right at all costs you'll only miss something. I am an auto tech and I learned that lesson. Retrace your steps,

One other possiblity and in a long shot is that the lifters are not bleeding down which would hang the valves open just a tad. When you put in a bigger cam the lifters are set for the smaller cam and once installed the bigger cams can push the valves open a bit. Do a compression test and see what the results are. Check all four cylinders and post the results.

**edit: We are trying to help, and being rude will get you ignored. **

Hmmmm - HKS cams stamped with lift information from a reputable source (Curt Brown) - I imagine they are proper.

By the way - the timing belt was never removed when these cams were installed - one cam was installed at a time with the t belt zip tied to each cam gear.
