Help! Car shuts off at idle
#17
doesn't feel "normal" to me. my last tt never did this. same exact symptoms here. does not stall, and then after "hunting" up/down, my idle settles right at 750-800 where it belongs. a new maf seems to eliminate the issue. then it comes back once i've pegged the rev limiter and blown(?) the maf ( just my experience, may or not be the cause ). annoying. high operating ( ambient i should say ) temps exacerbate the issue.

Apparently it appears to be normal, at least this thread
leads me to believe that, on COLD starts ... Thoughts ?

My issue was when coming to a stop the idle would drop and car would shut off but would start right back up. It was caused by 3 or 4 small leaks which the smoke/boost leak test revealed.
I had changed my alternator, battery, fuel pump, pump relay, hitachi maf etc and all it was was a few small leaks.
Good luck as we all hate to go through this!!

Its the oil pressure advancing the cams, then the cams re sync hence the hick up same at around 3k cruising. Almost a dead miss.
what i did NOT know.. if true.. was that the ( occasional) hiccup at 3k ( not as noticeable as the cold startup hiccup ) was also related(?) to the oil pressure/cam deal. every time i switch a maf though. the 2800-3k rough spot goes away. i'm not so sure the 3k rough spot is as common, but i defer to anyone that knows one way or another.
