P1237 code pending - and its not running...
2005 R53 - Chasing the above code. I had a severe stall/stumble on throttle-up as well as it idled like crap. I replaced the bypass valve and the idle is now smooth and continuous but still stalls/stumbles on throttle up. Next up is the code. I cleared all my codes (low fuel missfire on cyl 2 and a few others - yes it was almost out of gas) and the only other "hard" code present was a P1237 (upstream MAP). Ok... I can fix that. When I clear codes I always go back in and check/make sure everything is/stayed cleared. Well, upon recheck, it already has a P1237 pending...and the car hadn't even been started! So does this sound right? Maybe electrical (harness) as opposed to bad MAP? Its been nasty weather here since I replaced the BV so haven't gone back out to start searching. Just looking for possible direction to shorten the search
Thanks
