I have the 302 (5.0) with efi and noticed fuel leaking out on the passenger side fender. found out that my fuel pressure reg. was bad and was leaking fuel into the vacume lines. I replaced the regulator and it still ran bad especially when a load was put on the engine. I popped the vacume line to the regulator and it was throwin out fuel. THANKS OREILEYS. I went and got a new one and just put it on and now its still running extremely bad. it will first start up real good and idle well until I put it in drive. after a few minutes everytime i stop the engine sounds like its bout to die and when i give it gas it does die or gets really close to it.
Also the engine was rebuilt not to long ago and has been running perfect til just now. secondly the transmission recently slipped on me so i immediately towed it home so i wouldnt damage it anymore and eversince then it hasnt slipped again? I had a friend look at it and he noticed how hard my gas pedal was and immediately brought up a tv cable or something. its connected to my tranny and then goes to where my throttle cable hooks up. he said there could be something hanging it up in the tranny.... dont know if the two problems could have anything to do witheachother im only a begginer mechanic on a low budget so im lost. any advice will help thank you.

 

See if it has any codes from the computer. The fuel in the vacuum lines could have damaged some of the components.

 

just a heads up on the tv cable do not attempt to mess with it unless you know exactly what you are doing it is very touchy and you can ruin your tranny if you get it out of adjustment just 1/4 of an inch off. I know this from experience. Also in my opinion if you have to rebuild that aod save your money and get a c6 that aod is a piece of junk. I put 2500 dollars in mine and it is still a piece of junk bought one form jasper engines and let them install if for me.
