So I have a 93 T-bird, it's a 3.8. It has an unknown number of miles on it, so anything is possible. Anyways, when I hit the gas to accelerate it just stumbles and and jerks really bad. It acts like its going to stall, but hasn't yet. It has been stalling when stopping occasionally. It is not reliable enough to be driven. But, if i put it in reverse it acts perfectly and accelerates with no problem. So I'm trying to figure out what it is. I had a guy look at it and hook it up to the scan tool. There were no significant codes, just an ECT and canister purge failure. The fuel pressure was good, and I just replaced the fuel filter. What could be wrong? Is it a transmission problem? The guy I talked to thinks it may be a fuel pump. We cleaned the MAF, since I've heard it can cause to Ford to act like this. I'm very confused as to why it is ok in reverse, but not drive. But, any advice would be greatly appreciated.
