Re: SEAMS LIKE THE CHOKE IS STUCK BUT ITS THOTTLE BODY

Start with a visual inspection - vacuum lines off etc. - especially the one to the MAP sensor.

Then check the codes - it should give you a clue. It'll have one - or more, since the Check Engine light came on.

Tell us the codes, then we'll go from there. With so little information so far, it could be one of dozens of things.

What you saw with the injectors is normal.

Re: SEAMS LIKE THE CHOKE IS STUCK BUT ITS THOTTLE BODY

i was following my bud to go have lunch at his house on break at work, his 91 4x4 sub did the smoke thing, didnt hear anything about looseing power, 1 thing i can think of would be the EGR system, or perhapes the IAC, TPS, all those little controls on the engine, if one goes bad it will run like crap, anywho, do the paper clip thing to find codes, and then post them.

It could be lots of things - or even a combination of things.
But since he hasn't bothered to respond he's either stuck somewhere in the middle of nowhere and can't, or it exploded and killed him.

He wouldn't be so rude as to not respond would he?

When someone asks for help, takes the advice and never lets you know the result they aren't worth helping again. Little kids do that alot.
