The car has been running a little iffy lately. I'm getting codes 13, 32, 42, and 44. 13 and 32 are explainable, don't have an EGR and I've always gotten 13 even with a new O2. 42 is for the EST and 44 says I'm running lean. The car is an 89 2.8. I got bumped up fuel pressure and 3.1 injectors so it runs a little rich. The strange thing about this is that the car idles OK (part of the problem) but accelerating is fine under 4K RPMs. After 4K the motor spits and sputters and doesn't want to go any higher, it will sometimes, doesn't matter if hot or cold. I figured that this is some sort of spark issue then. I don't know whats going on. Plugs, wires, cap/rotor, and the module inside the dizzy are pretty new. Any ideas?

 

Anyone have any ideas?

New coil, O2, and plugs and the car runs much better but now will randomly drop down to idle, sputter, and then die. Then it barley wants to start up. Otherwise the car runs like it should.

 

Any help would be appreciated. I'm out of ideas and patience with the car.

 

could get module tested, pick up coil maybe? I have similar problem but with no codes. do you have pacesetter headers?
