Ok, so my MTX has been acting up really bad in a number of ways the past couple months. The biggest problem I'm having is a stuttering problem under steady throttle, it doesn't seem to happen at any one particular point it can be part-throttle or WOT and just randomly it'll stumble really bad as if the car shut off for a split second. I recently did the IAB and plugs/wires and after doing the plugs/wires, the stuttering stopped, but it is coming back again only a month later, and I dont see how the plugs/wires could be bad already. There was no oil in the plug wells, just a really really small amount in 1-2 of the back plug wells but not enough to even touch the plug boot. The next problem is that for some reason, every now and then my car wont want to start at all. It'll just sit there cranking and cranking and while Im cranking it, I'll see black smoke pouring out my tailpipes. Eventually it'll turn over and smoke black smoke for a second after startup but then it runs pretty much ok. The car definitely smells like its running rich, no idea why it would be doing that. 99% of the sensors on the car are new within the last 40k miles except the CID and CPS. I ran the codes and got these:
211-PIP Circuit Fault
214-CID Circuit Failure
528-can't find this code anywhere
537-Can't find this one either
542-Fuel pump secondary circuit failure
Any ideas?? This car is driving me nuts!!
