my car just started acting funny , if u crank it over it starts and dies inless u floor the gas and hold rpm high? anyone know what it might be?

 

Opti might be goin, might be the fuel pump.... chek fuel pressure.... any codes??

 

i dont have a scanner, yet...my dad got it running right last night but it is doing it again. i guess he just held the gas for a while and it was runing ok.. dunno

 

I had a very similar problem with my Z. It would start up fine, but would end up dying after a few seconds. The problem ended up being a torn intake elbow. Luckily, the tear was right where the elbow connects to the throttle body, so all i had to do was reposition the clamp past the tear and that fixed the problem. My car has not died after starting since this fix. Hope this helps. Good luck.

still wont run

 

Make sure you check the fuel pressure.

I don't know what else it could be.

 

Unplug the MAF and see if it will run. It sounds like unmetered air after the MAF. Do you have A/C? If so turn it off. Another problem could be IAC. When you push the gas down does it rev normally or sputter and kick?

 

I'm guessing its the IAC.. my '93 Z does the same exact thing. I think you can get it at Autozone or Advanced Auto Parts for around $60-$65.

 

Ha, I love LT1's. I just went through all of that, replaced absolutely everything, had good fuel pressure, getting spark...it was the ignition switch on the back of the steering column...$27, and took me about an hour to replace, shoebox has instructions on his site. Your symptoms were mine exactly. Would not start unless you got it to fire, and held the gas down to bring the rpm's up....good luck

 

behind the dash? i installed a stereo when this started to happen, maybe i bumped it?

 

no you shouldn't have been anywhere near it when you installed the stereo. It is mounted to the steering column. Its a PITA to get to.

 

also my power door locks decided to stop working at the same time

 

i am having the same problem....and am wanting to change the ignition switch....where are the instructions for this on shoeboxes site, i couldnt find it.....thanks

and oddly enuff, i noticed my power locks also, would lock by themselves, i would try and get out of the car and they would be locked??? is this related???

 

ok so a millions things can be wrong.wtf, dumb lt1

 

my dome light doesnt work either...
