Another Canuck joining this board. I was told by fellow Ontarians (Dave, Paul, Scoob, etc) that this is the place to be to get some answers...well, I can't wait then!

Welcome. What kind of answers do you need?
My car bucks under light throttle in OD or when the engine is under load. I was hoping to send my PL logs for someone to have a look at. These are the items that have been swapped out to try and isolate the problem:
- new ECM
- new ignition module AND coil pack
- new ignition wires
- cam sensor cap is Caspers LED type
- cam sensor is stock
Thank you,
Angelo

Fuel filter been changed recently?
-
Attach the logs here. Have you verified the fuel pressure is correct?

Hi Steve - FP rises with throttle input - checked with windshield mounted FP gauge. Fuel filter is relatively new, but could check again. Could it be any of these?
- cam sensor faulty
- incorrect gap on plugs? incorrect plugs?
Next step is to replace plugs with RTS44's and gap them at a tight .30 (as per Scoobum's recommendation). I don't think this is it because I had E3's in it before these plugs and the bucking was there.

I'm not sure of your mods but I've had good luck with the ac ones you mention and autolite 26 in my fairly stock car. I usually hit em with .035 but if scoboom uses .030 I'd say go with that as your climate is different. Have you at least pulled em to see what they are gapped at and what they look like? Could be a carboned up one or an oily one.
