Ok, My '99 Tacoma with 2.7l/5 speed is misfiring pretty bad at idle. It is also fairly hard to start. quite a few turns before it fires. The misfire seems to clean up with increased engine speed but its pretty damn gutless. I know its a 4 banger, but it can barely pull 4th gear on the fwy with 31" tires. I just bought it. Got a crazy good deal on it and bought it from my brother in law who bought it new. he only drove it about a mile to work each day and it sat a lot when he was deployed multiple times. It threw codes for cyl 1 and cyl 2 misfires. My first thoughts were plugs or wires or possibly a fuel filter. I installed NAPA's premium plug wires and whatever the reccomended plug was. its escaping me at the moment. I also replaced the fuel filter. What a difficult place they put that!!! anyway, no help. Still misfiring pretty badly. I also though maybe the coil packs, but its misfiring on cyl 1 & 2 and the coil packs are 1&4/2&3, so if it was a coil pack problem it seems to me that it would misfire on 1&4 or 2&3, not 1&2. my next thought is cam position sensor, since thats what triggers the ignition. Is this a common occurance? What else could be causing this issue? Are there common problems that these engines have?
Thanks for any help!
