Stressing on A/C

[gt96stanggt]

Well today my car decided to pretty much die on me and my dad. kinda felt like it was running out of gas but i had a 1/4 tank. It didnt want to accelerate at all. after i finally got it home... mind u it dies as soon as i turned into my cultisac (sp?) i let it sit for about 30-45mins then drove it and it drove fine.. the only thing i could think of is that i ran the a/c today for my dad and i hardly ever run the A/C. so maybe it stressed it out my engine? or I DONT KNOW!! any suggestions as to what it might be?

When you started it again how did it do? Did it die shortly? Maybe it's the alternator.

BTW get that offroad H pipe on if you don't have it on already

when i started it like 2 mins after it wanted to die, it dropped to like 300, so i just turned it off.. but after i let it sit for about 45mins or so it ran like nothing was wrong with it..


and im just waiting to get emissions and registered for 2yrs then its going on.

lol I feel your pain with the H pipe. How long did it run fine?

Check your fuel pressure it almost sound like your fuel pupm is getting weak and about to go.

Did it not start right away or did you just let it sit??

I started it like 2 mins after and it started up for like 1 min then the rpms dropped to like 300 and i hit the gas all the way in and it went up to like 500-700? haha so i just turned it off, went inside, ate, then went back out and it started up and drove fine.

Well then I would suggest cleaning your mass air and see if that fixes it but it sound like it may be on it's way out. Not the fuel pump like I thought before.

Start with the basics. Clean your MAF & IAT sensors, check your ECT sensor, check for spark on all 8 plug wires, remove all 8 plugs, and look for any oil or white markings on them. Check for stored CEL codes too

Check fuel pressure w/ and w/o vacuum, check your vacuum.

That should keep you busy for a while.

I had my air pump diconnected off of my factory H-pipe and my car did this exact same thing. I think your cats are not getting enough fresh air to work properl;y and loading up the cats creating a TON of backpressure.
