ok sometimes my car likes to idle really badly, and when i press the gas, it boosts hard, and sometimes even creeps, but it will accelerate very slowly. this is an intermittent problem.

i have an 87 T2 with a downpipe, HI-6, removed ACV/air pump, and ultra wires.

most people say its the HI6 malfunctioning, but when i first connected it, i did a bad job crimping and it came disconnected from the battery, so my leading plugs werent firing. and that was not the same as what is happening now.

 

Dude I can't help you here but I gotta say. D@mn I love the title of this thread man. Mack daddy.
peace out,
Charles

 

Will it accelerate very slowly while under boost? Sounds like it could be a vacuum leak. I have had that happen intermitently. Does it idle too low or just rough?

 

it either idles really good, or it idles at like 500 rpm really roughly

 

Have you checked that your TPS is adjusted properly, also that your BAC is working?

 

The culprit could very well be a bad vacuum line somewhere. I would check and recheck those. I never crimped but soldered my Pro-Pak, so i wouldn't have that problem. Also check your turbo inlet duct and make sure you're not taking in any more air after the MAF. Also the I/C hoses. Don't go by your stock gauge either, they're worthless.

 

how would i know if my BAC is working?

also how would i go about checking for leaks without spraying flammable aerosol into a hot engine bay?

 

Hey Funklord,
I found my vacuum leak by purchasing a stethescope from the parts store $10.00, but removed the little rod hanging out of it (cause its for finding vibrations etc.) and inserted a peice of hose 1/4' dia. or so, then just put the hose end near where a leak might be and you can hear and isolate it.
