Had a problem like that. The problem was a cylinder head valve sticking open. To find out if that is the problem have a compression check done.

Ok, here it goes, I had codes come up for cam and crank sensors. I replaced them. I have a P0303 code misfire. I replaced plugs, coil pak, and 3rd injector. It still gives me code and is missing terribly. Can't figure it out.
If anyone knows of any ideas to fix, please advise.
Thanks
glezman@gmail.com
same thing did anyone figure it out?
pretty much same problem haven't tried changing coil pak or injector but otherwise new plugs & wires! old plugs looked good but had a lot of miles wires were original. Still missing don't know what to do next!
