04 Rough Idle after Burnt Alternator Fix
04 with 144k+. Alternator caught fire recently and melted engine harness connector to alternator, part of the harness to this connector, and melted the 2 wire harness to the Intake Valve Timing Solenoid. The harness has been repaired, and a new alternator has been installed. Battery voltage is good, but the engine has a miss and vibrates if under 1200 rpms. I pulled codes P0300 and P1136 shortly after starting the engine. After researching this IVT soleniod here, this is what I can say to eliminate causes: oil was just changed a month ago, spark plugs were changed 10k miles or less ago, everything was in perfect working order before the alternator caught fire and melted the harness. I have replaced all fuses that blew when the harnesses melted and shorted. Im leaning toward the driver side bank IVT soleniod went south when the harness shorted, but I would like other's input.
Again running the engine above 1200 rpm's shows no miss, no noticeable hesitation, no loss of power. Anything 1200 or less generates a miss and engine begins to shake. Ive found the IVT solenoid on the internet for approx 150, and a post on here that they are straight forward to change (can't be as bad as changing the alternator...).
