I have searched the posts for my specific problem, but it seems I can not narrow it down. Here the systems:
The car idles fine and will rev up with no problems in park most of the time.
When I accelerate, it feels like the car is missing but will eventually pick up. Also, I will be driving along and I will let off the accelerator and the car will just down shift at approx. 40 mph. Here is what has been done the car. It is a 1999 Legacy Sedan 2.2 Limited with 106K.
New completely replace transmission – 65K (warranty done by the dealer)
Plugs, filters etc. – 65K (done by me)
Plugs (Bosch Platinum gapped at 44)
Timing Belt, Front and Rear Crank seals, cam seals, water pump – 105K (by mechanic)
This problem has been around for about 15k miles (since 90K)
One thing I did notice, one of the plug wires came off during travel and it stated missing really bad. I put it back and it is back were I started. Could this have fouled the plug by it firing with the boot barely on?
