changed tps now car has horrible miss....help??
I just changed the tps on my 2000 Ford Focus SE and now my car has a horrible miss. Changed the plugs and wires to see if that helped but it didn't. Car chugs under a heavy load and tries to stall when stopped. Wondering if the tps did not seal and could be causing a vac leak. It didn't chug until I changed the tps. Mileage on the motor is 30,xxxx and mileage on the car is 109,xxx. It is the 2.0 duel overhead engine. Any other ideas??
