bleeeeech 1 Report post Posted October 6, 2013 Looking at purchasing a 1989 320i. body is nice and straight, everything else is fine. however it was rough idling. What are possible causes for this ? Seller also mentioned that over 100 km/h occasionally the engine will "missfire" or incur loss of power in a quick burst before settling. Suggested it could be possible fuel injector issue ? Should i just walk away or could these be quick fixes ? cheers, Jazz. Quote Share this post Link to post Share on other sites

yng_750 247 Report post Posted October 6, 2013 Yea that sort of thing can be elusive, i would start with a good service, including plugs, leads, fuel filter etc.Then go from there. not usually expensive to fix but often you can end up spending money on parts you dont really need trying to find out whats actually wrong. so not a major but should definantly affect the price you offer. If you can work on it yourself taking $1000 off what you would pay for a perfectly running model will offset the cost and effort of fixing it. just my opinion Quote Share this post Link to post Share on other sites
