Engine Performance problem
1996 Ford Escort 4 cyl Front Wheel Drive Automatic 206000 miles
when coming down from fast idle the rpm surges.I have check fuel pressure 31psi at idle 34psi at 2000rpm.I also checked the egr seals fine, mass air flow sensor voltage readings fall within spec, vacuum gauge reads 18 inches steady check for plugged cat seems fine on the vacuum gauge, I also notice at -20 cel the car is hard to start I have to hold my foot to the floor but it does start and run ok sometimes it does stall. This problem is only when it is cold when hot no surging. Any ideas?
have the same problem?
