MIke D Posted June 15, 2008 Report Share Posted June 15, 2008 Some may remember my original issue with a rough running engine. For those who don"t PO300 and PO404 is where it's at... New twist. The car has been getting better all on it's own then Wham... back down to running rough again... Then it's better.... Then it's not... Well today I got a P1381.... This is wierd because it was running good today. Still backfires randomly into the intake. usually up hill while trying to accelerate but sometime as soon as i touch the gas coming off a stop. I'm about to get into the books again. I was about to just change the cam and crank sensor for the hell of it.. but this gives me a new path to go on... Cop didn't see it, I didn't do it! 93 STS 225,000 Miles 99 STS 111,000 Miles Link to comment Share on other sites More sharing options...
