Hello everyone, I need some advice for my car: I had the Cat replaced by a pipe a couple of months ago (which is legal here) to get a little more performance out of my car. This DID do the trick, not much, but noticable enough. The car was behaving beautifully when I got it back from the shop untill about three weeks ago. When Idling you can smell some unburned gasoline from the exhausts (and no: I'm not kneeling down to notice) and I get VERY frequent backfires. I even get them when taking my foot off of the accelerator at as little as 1500rpm. This backfiring is nice when you want to impress your 7 year old cousin, but that's about the only "pro" I can think of: it is not supposed to be this way... If it had been this way ever since the cat was removed I would suspect that, but all went well for at least 6 weekends of driving (adding up to about 500 miles). I also suspect my fairly poor gas-mileage to be a result of this: I get 6km to a liter (=1:6) (about 14mpg I think), while I hear of several other Dutch owners who get 10 km per liter (23mpg???) which is close to DOUBLE the mileage!!! If this can't be helped so be it: it isn't my daily driver, but it would be nice to take a longer trip without having to refuel so often (except maybe for the looks I'd be missing, which you usually get when pulling up at a gas station)... My car is going to the shop next thursday for its' annual inspection and since it's going to be there anyway I'd like them to look at this too. This shop has had some experience with the PRV-6 in other configurations, including the Renault Alpine A-310, but untill I came along they had never worked on a DeLorean. My father happens to know the owner of the place which is reassuring AND they are a member of "BOVAG" which means they are respectable and do good work. To make a long story short: I trust them with my car. To make it a little easier on them I'd like to know what would be the first thing to look at when suffering from the described symptoms. My guess would be either the engine is running too rich, or the ignition is off. Any other suggestions are more that welcome: there's an event in Germany next weekend I would like to attend, but if my car's still in the shop then that won't really work ;-) Thanks in advance from The Netherlands, JAN van de Wouw Thinking Different...
