I was driving up to tahoe on sautrday, nice and easy, and the car started to shutter really bad. I looked at the temp and this was the first time I have seen it above the half way mark. It was just a little over, nothing to worry about. Plus it was really warm out. So I pull over and let the car sit for a bit and try it agian, nothing. I also have a CEL now. So I turn around and get the car home so I can take a look at it the next day.
I hooked the pocket logger up to it to see what the CEL is and I got a misfire in cylinder #2 as well as an undefind P1400. I then checked the plugs and sure enought the cylinder #2 plug was dirty, real dirty. I cleaned it, along with all the other plugs to see if that would help and it did, but it was still mifiring. So I installed some new NGK BPR6ES's and a new valve cover just because. The new plugs helped, but didnt fix the problem. Then I replaced the wires, agian it helped but didnt resolve the problem.
My local speed shop recommended I replace the coil packs. But personally I would rather narrow the problem down if at all possible before I spend $150. Then I got the idea that maybe, just maybe the timing was off for some wacky reason. I reset the ECU and the car ran flawlessly for 15 minutes. I let it warm up then drove it. No shuttering, built boost just like it usually does. Then I pulled over and shut the car off. When I restarted it, it was running fine. I hooked the logger up to it agian and no codes were reported, yet. I got the car back home and as the turbo timer was counting down the car started to shutter and the CEL popped back on. Sure enough, the same two errors were back.
What I would like to know is there any way I can narrow this problem down without just randomly buying parts that *might* fix the problem? Does anyone have any tests I can run? Can someone tell me what the code P1400 is? Does anyone have any suggestions? I have another mode of transportation for now but I need to get it fixed asap. Thank you in advance to anyone who helps me out.
