i have a 1990 mustang lx 5.0 with a cobra engine I have problems with it leaning out under acceleration everthing has been replaced every sensor, fuel pump relays, ignition ive been through the wiring harness the car was orinallly a 4 cyl car I bought the car after someone had replaced the engine with the cobra engine the car has no emmisions at all on it but the engine ran fine for years the I had a miss at highway speeds then I replaced the ignition pickup in the distriibtor and the fixed that problem new mass air meter calibrated for 24lb injectors, I dont know what else to try I do know when I drive it when its cold it runs fine when it heats up it starts running and idleing bad the after a few minutes when it cools downs while idling it levels out and runs smooth. If u have any suggestions I would appretaite it. When I say I replaced ever sensor thats what I did. Ive been over and over everything on it. Hope u can help.
