i have 2 codes, in order p0102, p0440, and p1345. i am aware of what each one is. the vehicle runs and act perfectly fine. so i tryed deleting the codes, well the lights come back on imeditly. the dis and cat are not even 2 months old yet. when i put the new dis in i got the 1345, moved it a tooth ran perfect light went away. then a week or 2 later, these 3 codes show up.

 

If they came in that order, get some maf cleaner, follow directions on can and check your air filter. Make sure your gas cap is tight. Make sure the hold down bolt on distributor did not loosen up. Re-set and see what happens.
