Hi guys first of all I'd like to thank those responsible for posting the timing belt change write up it was very useful.

-I did this a few months ago and have been driving the car with no problems, it just seems a tad slower and mileage has gone down, but that may due to it being winter and having to warm the car up first.
-I have a 94 celica gt 2.2 liter

-I changed the timing belt and rotated the motor *without* the tension pulley tightened down so I the timing marks on the camshaft and crank moved a few teeth out of alignment. I went to realign the marks and started it but something was definately off. The car didn't want to rev up. So I moved the camshaft and realigned the marks a few teeth not sure which way or how many it was too long ago. *Next I started it up and it runs fine smooth, I did reset the timing back to factory specs. but it seems low on power and mileage.

-My question is how will the car run if the camshaft gear is advanced or retarded by 1 tooth. Will it be obvious with misses, slow to rev.? Or would it still run smooth just with a little less power and mileage like I have?


Thanks

i remember being one tooth off (can't remember if it was advanced or retarded) and the car wouldn't maintain idle and would just die.
roughly how much power (percentage-wise) does it feel you're losing? and how bad did your fuel economy go from what it was before (in mpg's)? the cold does all sorts of things to the car that makes it feel sluggish... cold oil = thick oil = more power loss... cold O2 sensor = more fuel dumped into cylinders... then theres the snow, the extra warm up time, and a bunch of other factors that come into play. just to give you an idea, my car does 23-24 mpg in the summer but does 20 to 21 mpg in the winter. the car literally gets tortured from the cold. a block heater will help your fuel economy a lot.
