I'm hoping that someone could help me with an issue.
I'm getting a misfire, it only seems to happen under mid-heavy load, and only for the first about 10 mins of driving. No codes come up unless I let it continue to misfire, which I dont. The one time that I did it was a random misfire code. P0300 or something.
Things I've done - Spark plugs, new MAF, new spark plug wires, new ignition coil packs. Possibly unrelated things - new alternator, new starter, swapped the box filter for a cone. Past the air filter the car is totally stock.
One other problem too, my idle is low, like 500-600 kind of low, a shop said it was the IAC and replaced it, it got better (it was dying on me if I didn't give it gas before that) but the RPMs still seem mad low.
Last. Problems that I KNOW the car has ( not sure if they're related but more info is usually better)
-Lights dim when I let off gas, which I think is associated with the low idle.
- What I THINK is lifter tick that goes on for like 30 seconds or so on cold start
- Bad valve seals (bluish smoke from exhaust if I idle too long.)
If you can point me in the right direction I'd appreciate greatly. I can do work just fine, but I'm no good with troubleshooting. In the end I'm an electrician, not a mechanic
Thanks in advance
