Hi everyone. I am having some trouble again. I have an 86 740 turbo w/automatic and every once in awhile it seems like the car just will not accelerate properly. Its almost like the engine does not want to accelerate past 2000-2500 RPM. It is wierd because the turbo spools up and is really working itself hard trying to move the car. It can barely even make it up hills and it just stumbles all over the place. The other day it got really bad and sitting at a red light, I turned it off. When I started it back up it ran fine, like there was no problem at all. I took it to a shop once before and they said they wanted to change both fuel pumps for the small price of $1,350.00. Needless to say I walked because the car started to run fine again and they were scam artists. I have newer plugs, clean t.b., new air filter, etc.. Basically it is well tuned. It has only 166k miles on it so I do not know where to start. I imagine it is something in the electric. Please help if possible. Thanks ahead of time, Joe.
