weird problem
weird problem well i pulled my car outta the garage today and was going to my friends house well a mile away from my house i forgot to get the movie i was going to return so i went back and got it and left the car running well before i got back to it the
car just died..well i tried starting it again and it wouldnt do anything so i opened the hood and look around but nothing seemed outta the ordinary so i tried to start it again and it fired right up...then i started up my driveway again and it just died but it started right back up and i keep going alittle farther and it started acting alittle funny like it wanted to die but it didnt well after that i never had a problem..i got to my friends house and i just let it idle for a few minutes and it was fine..about 2 hours later i get in it to go eat and few miles down the road it died when i was going slow down a hill...then i was like F it so i just went on the interstate and went home well on the interstate i had to cruise on 70 and it was doing fine for awhile till i was going down a hill then started back up it the rpms all the sudden just dropped so i hit the gas and it revved back up well i made it home alright after that and i dunno what it is...im guessing maybe the fuel pump, im going to get the fuel pressure checked tomorrow does anyone else no what might be wrong..the check engine light isnt on...sorry for the long story just wanted to tell ya everytime it happened..

Sometimes the MAF on my car got a flakey connection and it would behave like that. I would just get out, open the hood, unclip then reclip the connector a few times (to scuff off any crud from the pins) and it would be fine for another 3 to 6 months.
fuel filter, and if not go to autozone and let it die there and have them scan it??? weird sounds like the maf tho? if so on craigslist theres a guy sellind a very good one for 50 bucks!
lol im scared to even drive it anywhere,i dont think it will make it..it might be my IAC valve but i dont think i can check it by myself im not that mechanically inclined and i changed the fuel filter probably 5000 miles ago

man I think that I am having the same type of problems. I have changed the crank sensor, coil, cap and rotor, and opti. I thought I might have gotten a bad opti so I took it out today and replaced it. I am putting new plug wires on tomorrow. Let me know if you figure anything out. I haven't check MAF yet
Kinda like aircraft, GM has some redundant systems built into the PCM so that if something like the MAF fails, you can still drive it in Open loop/speed density fueling mode. It could be the MAF, it could be the connector. Have you checked your sensor Fuse in the underhood fuse box? I had some long tube headers that fried my wires together and popped the fuse that feeds the voltage to the MAF and O2 sensors.
checked all my fuses and none were bad..im takin it to the shop right now so hopefully my mechanic will be able to figure out what the problem is..lt1 chevelle im pretty sure its not my opti because it will run alright when i pull the maf sensor out and when my opti went bad the last time the check engine light came on and it was acting a little different, but ill let you kno whats wrong when i get it back

well i replaced the opti today along with the plug wires and put my car back together. I probably ran it for about 20 to 30 minutes without dying. The only thing now is that I have a bad miss. I don't think that I have any plug wires backwards, but who knows. if that is not it I am in big trouble. I don't know what else to do.
