i just recently did a tune-up on my D - had the fuel injectors cleaned, replaced vaccuum hoses, coil, plugs, wires, cap, rotor, seals, washers, gaskets, fuel filter, air filter, oil filter, main fuel line, etc. when i first started it up it ran okay, but after it would warm up i noticed the idle was really erratic. it would dip down to approx 600rpm, then shoot up to 1250 or so. it seems like the engine is on the verge of stalling when that happens. at this time it still drove okay, just the idle was bad. now, the problem is worse. in just 2 days time without driving it a whole lot, it has NO acceleration. there is a LOT of hesitation and its basically undrivable because of how slowly i accelerate. i've tried checking for vaccuum leaks with an incense stick with no luck - i also tried the propane tank trick that was suggested. i haven't been able to find a vaccuum leak, but who knows i might be missing something. it seems to me like something may have been shaken loose since it has progressively gotten worse? any advice for what to check would be much appreciated. thanks, bill 6976 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
