Car Forum / Volkswagen / Water Cooled Volkswagen Cars / November 200699 jetta vr6 slow acceleration
i have a 99 jetta vr6 , for some reason it idles fine but when i hit the gas pedal it stumbles or takes its own sweet time to accelerate or sometimes dosent even bother to accelerate, if i put my foot on the pedal slightly or real slow it sometimes accelerate ???? i am lost..i already changed the fuel filter ...any suggestions ????? ( i use 87 octane , could this be the problem ? but this problem was gradual, first it usto happen at about 60 mph now its all the time) ]but this problem was gradual, > first it usto happen at about 60 mph now its all the time) It appears that you got a load of bad gas on top of an already marginal filter. Where do you buy your fuel? A single filling of gasoline from the dregs of a slow-sell station could explain everything. Peter Wieck Wyncote, PA it happened on my way from delaware driving to fl and when i got here it got even worst..ok i'll burn as much gas out as i can and fill it up with premium 93. cause i usually use 87 > ]but this problem was gradual, > > first it usto happen at about 60 mph now its all the time) [quoted text clipped - 5 lines] > Peter Wieck > Wyncote, PA > it happened on my way from delaware driving to fl and when i got here > it got even worst.. When trying to purge bad gasoline, as a rule DO NOT add premium. The difference between low and high-test gasoline is ignition characteristics... premium is less explosive than regular, and may cause hard-starting. Add a can of Techron and fill with regular, try running that through the system. But the bottom line is that you may have plogged even the new filter if the Techron does not clear things up shortly. By any chance, did you run the tank nearly empty at this fill? And go to US-Gas or some such on US13 vs. a name-brand station? When in Delaware, stick to Hess or WAWA if you are looking for discount gas. Delaware sells E10 Ethanol as a rule, and some of the slower-selling stations can be problematic. Peter Wieck Wyncote, PA i think i filled up @ a BP then hit 95S but i'll try that techron with regular and see what happens...also when i checked the codes it said cylinder 1 is misfiring, could that be an issue ? > > it happened on my way from delaware driving to fl and when i got here > > it got even worst..

Sure could. From both directions. A fouled plug or bad wire could cause poor accelleration and a fouled injector could do the same thing. See how Techron does for the injector, and consider replacing the plugs if they are at their ~30,000 mile limit. Peter Wieck Wyncote, PA |
