I'm having problems with my m20, when I give it gas it stumbles and then revs up. I have checked the ICV and AFM. They are both working properly. I have also checked intake leaks and everything seems ok. I haven't done a smoke test. due to the fact that I can't move the car because to the current problem. I have done many test accordingly to the Bentley manual, and here are the electrical results. I wrote my results next to what they should be. I don't know what to make of it. I also have two computers that make the fuel pump react differently. They are both dme #0261200173, but one is from a 3 series and the other from a 5 series. does this matter? the 5 series one makes the fuel pump tick in a weird way, while the 3 series makes it sound like if its running extremely fast. however only the 5 series gets the car started. I ran the fuel pump with both and tested it with a multi meter and set it to test amperage. the fuel pump current specifications are 7.0 amps for 1988-1990 m20, my readings show .195-.245 amps in ac, the meter won't read dc in amperage readings. Do those figures make the fuel pump faulty? can that be the reason why the engine sort of cuts of when I give it gas? Somebody please!!!!!!!
