Re: 420A hesitates under load

Well it says you have a MAP and CPS sensor problem. Any problems with the MAP or CPS will normally cause the car to run like shit. Buy a shop manual at AutoZone and it'll show you how to test all the sensor with a voltmeter to see if they're bad or not. Test the CPS, MAP, and TPS. The CPS will throw the misfire CELs because it doesn't know where the crank is and doesn't know how to fire in correlation to it's position. I'm sure once that is fixed, the others should go away.
