ok it seems like when I start it or when I hear the loud sucking noise. Which I guess could be open loop or the IAC is open or whatever I get big puffs of black smoke, which I know its fuel. Whats the cause of this. 350 TPI bran new TPS ( my TPS may be off because I dont have a digital volt thing), IAC , MAF and relays

 

anyone? please know whats going on

 

btt

 

this board ****ing sucks if it doesnt interest u dont reply so **** this ****.

 

your head gaskets blown... how to fix?? get some rtv and shove it in your eyes and let it site for 4 hours.
jk man i really have no clue how to fix your problem but what color is the smoke is it from richness or oil??

 

its from richness....i can smell raw fuel when its in open loop

 

"ok it seems like when I start it or when I hear the loud sucking noise",
thats the iac opening.
when the iac opens it needs more air, when it opens wide open and makes a lot of noise just idleing that usally means that it is set too low and it tryies to save itself and opens the iac and when it does all that crap the gas managment is not too accurate how i know i has happened too me and i had the iac set way too low.

 

ya it only smokes when I hear the sucking noise

 

'89's don't have the self adjusting TPS? I know the self-adjusting TPS's started in 90 for the V6's...

Definately get a voltmeter and check the TPS out.

what exactly does IAC stand for?

 

i think idle air control makes sense to me

 

yeah mine has self adjusting TPS. I just cant get it right on.
