2004 IS300 Manual Swapped
Hi everyone, hoping to get some advice. Just finished the install on my BC 264 cams along with the whole timing belt service, did an engine break in per Crower of 20 minutes at 1500-2000 rpm with an engine break in oil. Started right up and ran great, no issues at all. Drained the oil and refilled for a test drive, and got a CEL/flashing TRAC light almost immediately. Got it scanned and codes were for Cyl #1 misfire and random misfire. It idles fine, runs fine, and doesn't seem like there's any misfire at all (my Civic had a misfire issue back in the day and was nothing like this). I replaced the plugs but did not do the wires, and the connectors for the coil packs were fairly brittle. First step is new wires and connectors, but figured I would ask if anything else could be causing my CEL. Thanks for any advice!
