engine lite

yesterday when i got on the interstate my D was acting like it was almost trying to slip of miss then my check engine lit started to blink when i let off it quit blinking andhasn't done it again.


last week i took to the dealer with the check engine light on they cleared it way just the calatic converter and he said just goahead and drive it but to get a new one sometime soon

any ideas???

Have had a similar problem, turned out to be the pickup assembly. This part is underneath the cap and rotor, and spins with the rotor. This part doesn't get replace with a normal tune up, so thats probably where I would start.
