![]() This sucks! I can't push my throttle past 1/4 or my stang sounds like I drove it into a pool. I can't even race the honda's over here in Miami and I have a 12 second car. What I noticed was that my fuel pressure gauge pulses between 38 & 44 psi while I'm idling. It never did this before. If I adjust the fuel pressure in any direction the pulsing will stop temporarily but will return to pulsing once I drive the car.
I would suspect a head gasket leak but I don't have any unusual water loss. You never know. I always run on the rich side and it smells like I do also. I bought a new TPS and I cleaned my EGR with short lived results. Please Please Please, if you find out what let me know.

![]() past quarter throttle, then it falls on its face huh? i had the same prob. with all 3 of my mustangs. and 2 of my buddies. MASS AIR SENSOR. for some reason they like to go bad. its either that or your tps, but you said you already replaced that. it is a possibility that it is something else though. like a faulty fuel pressure regulator, or pump. but if you have an extra mass air laying around try that first.

![]() Ahhhh buddies falling on their faces pissed drunk. I have some of those. LOL. Anywho, I tried my stock mass air and the problem goes away temporarily. I even tried a different computer. I had a similar problem years ago and it was a disconnected vaccum hose.
Hmmmmm. Anything else I should look for? I'm gathering all the info I can before I work on it. |

![]() Thanks. I checked it out. The only reason I started another thread
is because the ODD thread was so long and I thought no one would see it. I was wrong lol. Thanks again. |
