change timing belt should not have any affect on engine performance, unless the old belt was broken or very loose.
if it struggles upon acceleration, i suspect the timing is 1 tooth off,
it had happen to me, start up and idle fine, but no power upon acceleration.

yes it was VERY VERY loose it had 240000miles on it. it still gets up and goes really good,its renning like it has a slight mis ,reallyslight mis. ps i had the car since it had 14 miles on it

Yeah your off a tooth for timing. If its only a tooth off usually is runs just not so great just like your describing.

If I understand correctly, you had the ignition timing "tweeked" while the old belt was on there to compensate for the stretched belt, but haven't reset the timing since the new belt was installed. In that case, yes, you should reset the timing before messing with anything else.

update checked ignition timing with light and it is a little more than 10 degrees off, it is a little to the right of the 0 mark,standing on the passenger side looking in

Wow I never heard of car going 240000 miles with the original Timing Belt. Amazing. But I agree with others that your timing is 1 tooth off. Fix that and your good for another 240,00 miles

That's pretty retarded (in a timing sense).

Take a paperclip and jumper the TE1 and E1 pins on DLC1 (DLC1 is the test connector up near the passenger side firewall...the underside of the cover shows the locations of the pins). With the tranny in neutral (and the parking brake well set), check the timing -- it should be 10 degrees BTDC (the 10 to the left of the zero when facing the engine from the passenger side). If not, loosen the two distributor bolts (one underneath the dizzy, one to the left of the dizzy), and rotate it a smidge until timing is 10 degrees BTDC, then tighten down the dizzy bolts. Pop loose the jumper on the DLC, and recheck timing -- it should be in the 5-10 degrees BTDC range (it will wander a bit).

If that doesn't fix your problem, then, as lots of others have mentioned, your belt is a tooth off, although I think your timing would be off more than that if it were a tooth off (although the number of degrees of timing per tooth escapes me at the moment...)

will do in the morning
