Well I noticed it once or twice Friday, and then a lot Saturday after it had been driven for a while, and then a lot today.
It misses about every 10 seconds at idle in gear, but not in park or neutral. This is accompanied by a very slight drop in rpm's.
It lugs or lurches slightly under easy acceleration.
Then in WOT, when the turbo is boosting, it sounds different. It makes a wierd fluttering sort of noise, and the the car seems to jump very very slightly in accordance with the fluttering, but there does not seem to be any loss in power or if there is it is not noticable.
I purchased a tank of gas on the way to Brent's last night, and have been wondering if maybe it was some bad gas, but it did it slightly the day before on a 1/4 tank. To cover this base, I have added in some Lucas Fuel system cleaner and some Heat to remove any water that might be in the tank. It has not been long enough yet to know if this fixed it yet as I am still above a half a tank. At first I was thinking it was due to all the heat in the atmosphere added to the turbo heat, but it does it at night, in the morning, etc...
Could it be water in the gas, just plain bad gas, a fouled plug because of my rich *** tune, fuel filter? Also, the air filter has a tear where it it is held down by the hose clamp....could that "air leak" be causing it? I doubt it but maybeish...
I want to see how it does with these fuel additives first before I go any deaper, but any help or insite would be greatly appreciated.
