ERIC!! Thanks to you i will be graduation UTI Automotive school friday, you inspired me to start working on my own car and got very interested on working on cars and pursued the field. Should have a opportunity with AUDI or Subaru dealership soon, so thanks so much. I do have a question tho, My car recently just had terrible idle issues and you would think i would be able to figure it out but i dont have time really to work on it or the space. The car is Surging. idles normally at 750ish but dips down till its about to die but jumps back up. I was thinking IAC but not sure, i have a 94 Galant. What are your thoughts? when im sitting there just watching it dip down, i brought the RPMS up to about 1500-2k and noticed that it would cough or skip. when im driving around i dont notice it at all, thats why i was thinking IAC but again what are your thoughts? Thanks eric!
