ok here goes my 1990 toyota 4 runner 3.0 v6 has lost power while accelerating after changing the timming belt could it be a tooth off on one of the cams also when the crank is at 0 is the rotor supposed to be pointed at number 1 cylinder to indicate tdc it idles nice and smooth and starts rite up i cant figure it out

 

Not one single period in that run-on sentence. Makes it a little difficult to determine what the h*ll you're asking or telling....

First, did it ever run right after the timing belt replacement? Or is this something that just popped up?

Second, have you checked for CEL codes yet?

 

You need to check (set) the ignition timing, using a timing light. A possible cause of your symptoms (if I can figure out what it is you're describing), easy to check, and you've got to do it anyway.

 

sorry for the lack of punctuation i got it running good now. so i need to do the ignition timing. also the only thing it does now that i cant figure out is. it seems to kinda hessitate at around 3,000 to 4,200 rpm.but after that it accelerates fine.
