Hey guys,
Did a few things this weekend now the cars runny crappy. I swapped my ECT sensor. Had the battery disconnected and decided to clean the MAF with electronics cleaner. It didnt look dirty though. When I started it back up I forgot to plug a plug wire back up and of course got a misfire code. I already had a ECT code. So when I figured out I was dumb I hooked the plug back up. ANYWAY TO THE POINT... When im driving I get a intermittent hesitation like 4000 rpms and below. I will start hesitating and if I hold the same gas pedal pressure after 3 or 4 secs it will suddenly kick in like a turbo and have its power back. Could I have screwed the MAF? Im going now to get my codes re-read at autozone but any help would be appreciated.
Thanks,
Erik

Ok I took it back to autozone. More CEL's from before. I didnt get the codes like a dummy but One had something to do with air/fuel metering, another with the bank 1 primary O2 being bad and a cylinder 6 misfire. All out of nowhere. And I havent touched cylinder 6 for anything. I just disconnected the plug wire by the ECT to get to it better. Thanks for your help orangeapeel. I just replaced the front O2 with a bosch 1311 or whatever and waitin for it to cool down so I can check the plug wires. Damn car

ok fellas new MAF didnt work but I inspected the #6 sparkplug and wire and it was fine. #4 plug wire was hard and burnt some from resting a lil on the header. I replaced the driver side primary O2 as well. Its still hesitating in lower rpms and up to half throttle. its intermittent but persistant. At full throttle the thing runs fine. Could the one bad plug wire be jackin me up like that? Those MSD's have less than a thousand miles om em.

I'm having some what the same thing happening on my 2002 SS with 115,000 miles. I can not get a PO300 code to go away. I get the misfire at low rpm seems to clear what at higher rpm.
