Finally getting my ZR-1 back from Corey's!!!

[EvanZR1]

They very well could be, I just searched the spreadsheet I made of all the receipts/maintenance I'd been given on it, and could find any mention of the coils ever being replaced. Guess it may be time to pull the plenum and do them. That would make sense as that's more kind of thing I'd associate the rough running/missing with. Guess the white smoke would be from unburnt fuel? I did notice a rich smell when this started as well.

also did you ck to see if you map sensor hose at the back of the plenum might have come off???? this will cause that to . also you can do the mat sensor relocation yourself .sure helps if you drag the car at the strip .before i moved it the sensor would read 170 deg while idling in the staging lanes . now it get max 5 deg hotter then the outside temp

[EvanZR1]

Not yet, will go check it now.

give corey a call .believe me he will help in any way he can . he solved my problem over the phone many times . he is a true class guy

[sammy]

understand the frustration , dont know how well you know corey, he and i go way back and dont worry he will never leave you hanging. he is one of the most honest guys i have ever met. just wanted to share to put you at ease

[EvanZR1]

Oh, I'm sure Corey will be all over this as soon as he gets time. I know he's at BG, so I don't expect an immediate response from him. Checked the MAT sensor, and it's plugged in good. The thing that worries me the most is the oil, it's not just a little bit, there is a hand sized stain on the concrete under the car, so I'm very worried about that irregardless of what else is going on.

[sammy]

where is the stain located

[EvanZR1]

Directly under driver's side header collector (actually dripped on the header). Pretty much in line with rear of engine on driver's side.

sounds like a bolt may have backed out on the headers. your best bet is to call corey

Corey is indeed here in bowling green. He says that there are any number of things that could be causing your issues but first and foremost the O2 sensors could be a problem. Your injectors are freshly installed so more than likely they are ok but you could have an injector driver issue in the computer. Coils are original but they didn't show any signs of weakness on the dyno, but you can't rule them out completely. The oil leak is a concern for sure, probably the header stud on that side. He says he will call you first thing on Monday when he gets in the shop so you guys can make a game plan for getting her fixed up.
