shitty idle.. poor acceleration. all the things that your experiencing now.
see above for explanation on what the cams do..

wilson is talking about the cps.
but moral of the story is.. IF things arent TDC and your timing is off.. you will have shitty engine proformance.. + hazard

You can stop the cams from spinning by just putting a 10mm socket on one of the rear timing belt cover's bolts (one of the four behind the cam gears) and rotate until one of the spokes binds on the socket/extension. Have someone hold it in place if you can't work with a wrench in each hand (sissy.).

Don't know if that's the right way to do things, but it's worked great for me and keeps it as a 1 man job
Turn the crank one full rotation (DO NOT ROTATE VIA THE CAMS) to move any excess slack to the position between crank and exhaust cam.
