Bought OBW with 46k. Roadtested fine. First time it rained the car started to hesitated when pressing accelerator pedal. Ive had it to two dealers and a real good tinkerer. The plug, wires and fuel filter were changed. Then I was convinced it had to be coil. I changed that ($104.00). It ran okay until the next car wash with an undercarriage cleaning system. It seems to have three problems that are either related or not. 1.) after the carwash or a real rainy day it hesitates immediately. I step on the pedal it coughs , it goes , it coughs, it goes. That goes on for a mile or two and then intermittent and finally seems to clear after a day or so. 2.) from then on once; the car has been run and shut off, if the car is restarted while the engine is still warm it will hesitate the first time I step on the pedal. Dealer theorized that this was caused by the different temperatures of fuel in lines and the fuel tank which confuse the ECU. 3.) when the car is cold it seems to vibrate pretty heavily when weight is add (going up hill) The car now has 52k and warranty is running out so help would be much appreciated.
