Tracking a WOT misfire
Been trying to find this misfire foreeever.. idles perfect, runs great, takes off well at 1/2 throttle (well, 1/4 throttle til like 3k rpms, then 1/2 throttle boosts hard) any over 1/2 throttle and it studders and MIL for random misfires (could be any cylinder, usuaaaly 2 or 5 for whatever reason).
What I've tried :
- plugs
- coils
- injectors, seals,
- compression test - 170 on all cylinders (roughly)
possible other issues im debating trying...
- maf
- ecu
- fuel pump.. maybe?
- catalytics?? (has a burning of cat kind of smell when it sits at idle for a while in the shop, but maybe I;m mistaken).
Any input for other ideas? Thanks!
