2 questions

1. if our computer pulls the timing back then why do we keep bumping the timing.

2. my car has a hiccup once or twice a month. i will be on the throttle ever so slightly around 2200 rpms and it kinda acts like the engine dies and then it kicks me back in my seat for a split second and then all is fine. has happened three times in the last month and a half.

the puter will advance the ignition timing XX degrees from the base timing you set. so lets say (making numbers up here) that with base timing at 10*, total timing would be 40* (delta 30*). by advancing the base timing to 14*, the total timing would be 44* (still the 30* delta, but the initial 4* advance shifted the timing points across the board).

any codes (the CEL does not need to be on to have a code stored). i would go over the ignition (plug wires specifically) for the sporatic miss. it could be a lot of things though.

good luck.

Our comps only pull timing during shifts.

thanks guys. i replace plugs wires cap and rotor yesterday. if it happens again i am going to monitor fuel pressure.
