Well the 104s are in, the coils changed. The maf I put in ws junk!! So the old one is back in. The SES light is off!!! So my guess is that it was fouled plug or that corroded coil pack. I also found and fixed and vaccuum leak. Also put in 180* t-stat. So now the next step is headers!! Thanks for the limks for the headers guys! I also had another question. How restictive is the stock down pipe when you have the cat u-bend and resinator deleted and a 3" pipe to replace all that?
