I have a 94 Del Sol S with the 1.4 non VTEC that is runnin like shit. When i baby the gas it runs semi shitty but will pick up and rev up but when i give it any gas what so ever it sounds like a subaru deep rumbling like its running too rich which leads me think its the MAFS but i was wondering what anyone else had to say what the prob could be please Answer my thread thank you
