Figure this one out...**update....problem solved**
**UPDATE**
Well, sort of solved.... MY SDS DRIVESHAFT JUST FAILED! (on my way home from work)
Apparently theres a presspin in the drive shaft that came loose and has gouged a major groove on the inside of the shaft housing.
And of course it's a mere one month past the warranty :squint:
**END UPDATE**
So I finally got all the exhaust leaks in the RIPP headers plugged up as well as a better flowing cat back installed (3" NON-mandrel w/a 2.5 flowmaster). It definately made a difference.
The car now idles WAY high on cold start-up (close to 2000 briefly, then settles down to about 1500 for a couple of minutes). Now, I understand about cold weather start-ups having a faster than normal idle, but this seems a touch excessive, and it wasn't doing this before the exhaust work.
Additionally, the now-sealed exhaust did NOT solve my primary problem: Code 300 (random multi-cylinder misfire, which up till now was the only code I was throwing), and a decided lack of smooth operation or power (changing spark plugs tomorrow). This thing chugs, sputters and spews brown smoke like no tomorrow.
The funny thing is, that every once in a while it smoothes out and seems to be running fine...but only when I get a new set of codes: 137 and 157 (bank 1 & 2 sensor 1's no activity). :twitch:
So.. if the O2 sensors AREN'T throwing a code.. the car runs like crap... but if the upstream sensors go inactive, the car smoothes out dramatically. :bash:
Either way I'm running pig-rich, and my milage still sucks. :bash:
