A garage just changed the timing belt and water pump on my 98 Pathfinder SE and now it drives like crap!
From a stop, there is a delay when I push on the gas pedal before
acceleration starts. When moving, acceleration requires the gas pedal to be pushed much further than before. Again, there is a delay and then the transmission frequently downshifts seemingly two gears causing a big spike in RPMs. The vehicle also struggles to maintain highway speeds without downshifting unless I am heading downhill. Lastly, when it is accelerating I have to keep the gas pedal floored to keep the transmission from downshifting prematurely. Besides ruining driving pleasure, looking like a "boy-racer", and the stress on my transmission this is obviously affecting my gas mileage. I am down to 13.5mpg highway (from 15.5-16.6 prior).
The garage is going to take another look at it. PLEASE pass along any advice/ammo to help me get this fixed right and quickly.
Thanks
