Troubleshooting Request! [SOLVED] Options

[rave2n]

Hello all. On my way home from work this evening, the cellie died.

I was just taking off after a light, and it started to feel like it was stalling in 1st when the gas about half down. It seems to have recovered and was going alright. Drove normal...til the next light. Did it agian, but worse.

After stalling completely while going 35, pulled over. Had trouble starting up, but would start. Idle was crazy, but tapping the gas you could get it up to 4k rpm easy. That didn't last long either. It started to drop asoon as I hit the gas after that. Now it'll have a really rough start up, then run like crap for about 10 seconds, then just dies.

I checked for any obvious leaks or anything of the sort..nothing. My limited knowledge of engines is a hinderence atm. I do know, you need air, fuel, spark. I have air, I have spark. So, my question is...do you guys think my fuel filter, pump, or injector is bad?

The spark plugs are less then a year old, the only recent thing i've done is got a oil change, and put in LED BA-15 bulbs in my rear lights =P

Any assistance would be greatly appreicated, as right now its sitting in a parking lot of a not so wonderful area. Hoping its something I can fix quickly and available at a local shop..

Yeah, clean the IAC valve. It may not work, although more and more I'm wondering if it will - not only will it not hurt anything to do it, it'll help to eliminate one more possible cause.

Looking at your RPMs, I don't actually think it is a vacuum leak, you'd be idling way higher and more erratically if it were a vacuum leak. Pull your intake off your throttle body and clean the hell out of it with carb cleaner or better yet, sensor safe cleaner stuff. You can clean it w/the engine running, just pull the throttle cable up to open up the TB inlet so you can get inside that flappy opener thing. Again, I know my language is awful, I don't know what the stuff is called, (throttle body butterfly valve? IDK?) but I know what I'm talking about - and if it doesn't work, it won't hurt anything at least.

Definitely, definitely, definitely get that IAC valve cleaned out, it has often been the culprit of similar problems for other members on here.

You said you have no CEL. You're positive your CEL bulb works though, right, it should illuminate with the key in the ACC position.

Will do definately on cleaning that IAC.

Yea, I downloaded all the PDF's and printed them out today, and through the process of checking CEL light, and stored codes. I would just get no codes, it basically said everything is normal..even when doing test mode over normal. Thanks for all the help so far, been asking people i know at work, have got alot of "Oh well when I worked on my small block chevy"...yea..that doesn't help.
