'85 1/2 With a Backfire
Ok, calling all 944 Guru's- I just picked up a beautiful, garage kept, 1985 1/2. Everything on this car works! However, when I turn it off, more times than not, I get a backfire. The car sat for 8 years under a cover in a garage, but it started right up with a new battery. Everything seems to be connected. Any ideas? Thank you for your help!

Sounds like a great find! Congrats.
However, if it sat for 8 years, before you do anything at all, please change the cam and balance belts - ASAP. You've got an interference engine there, and if the cam belt breaks, you're gonna have some very unhappy valves and/or pistons. The maintenance interval is usually 3-4 years or 45,000 miles. 8 years is about double the life expectancy, so you're living on borrowed time. I wouldn't even start it once more before changing the belts!

But first, the belts!

The Kevlar timing belt is on order. Until it gets here, I'm hoping to get the backfire fixed.
Thanks! |

My 944 , acquired Xmas 2011 was running on a belt set from 1999
 The balance belt was broken and jammed ; the timing belt was severely cracked - the PO had dodged a bullet for sure and I held my breath of the drive home... I've still got the original clutch , which one day will go bang . Rubber sucks!
