My 1998 Escort 1.8 SI is nice to drive and handles well however; it does not have the expected power or acceleration. New air filter and high quality oil made no difference. I don't expect a racing car but when 1.25 Fiestas out accelerates you, there must be something out of tune. At idle the engine 'hunts', I have a Gunsens Gas Tester to check the CO but do not know the recommended reading or where to adjust the mixture. It may be more than the mixture, or maybe the car is just designed to be slow, does something need cleaning or replaced? Before I book the car in for an expensive tune up, has anybody got any suggestions that may make this car more responsive!
Many thanks in anticipation
