Subject: 96' LT4 Ignition problems,,,,,,, by Arisa on 2012/3/2 1:41:59 For starts..... "Arisa" AmsOil air filter, Throttle Body Bypass, LT1edit, Hotcam, Ported heads, LT's, Mezere EWP, Custom exhaust w/Random Metal Matrix Cats, & MagnaFlow Mufflers, Fidanza Flywheel, Stage III Clutch New knock sensors MSD 8.5mm plug wires NKG Iridium plugs Opti has 20K or so on it and 8 or so years Plugs and wires have maybe 300 miles on them That should cover the important stuff. Now to the problem. When I start off from a stop or roll gently into the throttle the engine bucks and misfires like hell. It violently shakes the car bad. I can hammer it off the line and she runs mean as even and I can drop a gear or two to get the rpms up before rolling in and she is fine. Up until the problem started I could cruise fine in 6th at 60mph and roll in to it to pass without issue. Now she is pissed at 60 in 6th. I've looked the plugs and they look good and I've ohm'ed the wires and they seem in spec to. No burns or cuts or cracks on/in them. The car has had maybe 30 miles put on it with this problem. Thoughts? Suggestions? Prayers? lol As a side note...not sure it is related but more info always helps....When I bring up the OBD on the dash I don't get the options of 4.0, 4.1, or 4.7 (PCM related functions) |
