RE: P1152 engine code
Well i checked out the plugs they look great. so after swearing and complaining I think it just might be the tps. tps go bad at spots that they are always at idle and 55 alittle different and it is fine which is how it is running so i ordered a tps and now am going to try that in the morning

RE: P1152 engine code
Ok, I hope the new TPS works, but if not, I just had a talk with my brother.
When I heard it might be an injector problem, I called my brother who is at Wyotech. He said that it very well could be an injector. I asked if I should check my plugs and he said that my sputtering problems was so rare that it would probably not show any effect on the plugs, and my best bet was to pull the injectors and check. I couldn't do that last night, but I gave him the codes I had running(P1151 and P1152). He ran the problem by his teacher today and they found that one code is a lean running code, and one code is a rich running code...in the same 02 sensor. My brother says this should not be happeneing. He told me a good step would be for me to take off my MIL eliminators and see what happens, if anything. So yeah, if that TPS works, that would be awesome, but if not...just keeping you updated on what I have found on my end.
Thanks for helpin bud.

RE: P1152 engine code
well the light came back on so i decided to check fuel pressures im at 30 with the key on and 26 while running which sounds low if i unplug the vaccum line it goes up to about 40 and runs much better so it sounds like i might have a bad fuel pressure regulator

RE: P1152 engine code
you found out anything new. I pressurized the fuel system and I have a drain back problem the system will not stay up to pressure as soon as the pump stops i lose all presure. something is not right on the rail or the pump i guess. we just had a major winter storm in michigan 4 in of ice so i wont be working on it again for a couple of days but i ll let you know

RE: P1152 engine code
If you read what the code means, you are having a rich condition, so you are not having a low fuel pressure problem, or a fuel pump problem. You are making this waaaaay more difficult than it needs to be.
IMO, it sounds like you have a set of bad MIL eliminators, did you cross the wires for the MIL's by ANY chance when you plugged them in? You can return them for a new set. I would say just put your original mid-pipe back on, but I don't know if you did the install or even have it anymore.
