Sorry dude, as i said, the inconsistent idle quirk went away after I re-re-readjusted the tps and set the idle speed with the jumper.

That being said, the only problems now are:
A) when revving engine from under the hood, between 1000-2000 RPM, there is a random misfire.
B) On a hot day, when the engine is hot, shut down... and say i go inside the store for 10 minutes... come back try to restart it... it will misfire, stumble, and all that good stuff. Sounds like a 4 cylinder engine running on 2 cylinders. If i can keep the revs up, it runs fine. Or if i go for a quick drive (5-10 seconds), the idle is back to normal. Mind you, it hasn't done it since i re-adjusted the tps for the last time, and set the bac properly, but i'm sure it will if the conditions are right.
C) If the car is not COMPLETELY warmed up... like 80% through its warm-up cycle, it will stumble and hesitate above 5000RPM it seems. Boost/no boost seems irrelevant.
D) There is a boost spike@10 psi... it then settles down to 8-9PSI, but i dont think it should be that high to begin with, considering i have a stock motor, with no mods aside from Autometer boost gauge. Stock boost gauge is VERY inaccurate, which is why i think the boost sensor might be fubared.

Now my fingers hurt. Your turn

 

out of ideas? hehe
would a clogged air filter cause this? I'll try idling it without the filter and see if that's the case.

Rip the air filter out. Do you have cats? Ground your boost sensor (for ***** and giggles) then run some techron through it.

 

Come to think of it... all signs point to leaky-*** injector, no?

 

Yeah i got cats... but my rb pipe and presilencer are in the mail ummm... already ran marvel mystery oil through... nothing

 

Run techron, it's meant to clean injectors, not lubricate your engine and eat up carbon

 

How do I concoct this techron? Better yet, where would I procure this techron?

 

Hah, chevron techron injector cleaner. Almost any car parts store has it.

 

YOU LIE! I live in canada. Canucks don't have parts stores.

 

Here's the thing though... my car never floods :P I just feel that the injectors are the culprit of my misfires and horrible MPG.

 

Hmmm, you're right, you canucks don't have anything. Well, find some suibtable replacement (Beer maybe? hehe) and stick that in there, get new plugs, wires, and fuel filter too.

 

yeah I think the fuel filter hasnt been changed in a while... plugs are new wires are tested and good...
Thanks!

More suggestions are welcome!!

 

I have another suggestion, give me the meshies and it'll get better! I promise :-D You can bypass the fuel filter if you have a tiny metal pipe or something to jam in there temporarily, that'll let you find out if it's causing the issue.

 

hahah ... the meshies are yours... as soon as you send me a new TPS, AFM, ECU, Boost sensor, and injectors

 

Ouch! That's gonna be a difficult one! Hehehe, maybe after I get the megasquirt hooked up I'll think about it!

 

Any other comments?
