Ive posted this in other forums thought i might try another. Here is the problem im having with my bird the car has approx. 135K miles on its V6 MPFI engine and the tranny was rebuilt about 2 years ago.

1) First off when its been sitting for a more than a day right now it will not start it just cranks, i have to shoot starting fluid into the throttle body to get it to start then i have to hold it @ about 2K RPM for a few sec (approx 20-30) sec otherwise if i let off the gas it will stall out. After its warm i can then turn it off and it will start back on its own.

2) When i drive it say trying to accellerate or go up a hill it lacks alot of power and sometimes will back fire or feel like it is going to stall.

3) I have changed the cap/rotor/wires/plugs and O2 sensor, I have also done a fuel pressure check like with the key in the ON position the psi was within factory specs and with the engine idling it was also withing factory specs. I have also tried running fuel injector cleaner also with no luck.

*alot of people have suggested a clogged or restricted exhaust system or cat. I dont notice the cat glowing but it does get really hot i dont know how hot i could say as if would be abnormal or not. The muffler is a flowmaster muffler that was installed about 3 years ago. and the cat has not been changed since i have owned it for the last 3 years.

Any suggestions will be great im trying to avoid taking it to the shop. Im going to start using this as my daily driver and start restoring the interior, while i finish up my 70 Camaro

 

check the cat with a temp gun or have a shop check it, check the filters, maybe the sock in the tank is clogged up or fuel filter, check volumn too not just preasure.

 

V6 engine huh! Check your injector coil resistance. Should be 11.6-12.8 ohms. Do a search on this form for my name FJK. I just responded to a post about 6 days ago & explained the entire deal.
