Sorry about the re-post but I got no response in the EG forum, (Vtec SOHC Kick-in seems to be popular )

Hey All,
I have a 92 Civic CX that I just did the timing belt on. Took about three hours, including the waterpump using hand tools. Lucky for me the crankshaft pully came off without breaking any tools or myself in the process. The marks were all checked out and everything seemed to be lined up correctly as per the manual. Checked twice and rotated the engine by hand, everything looks fine. Put the car back together, go for a drive. Runs and drives OK until about 4k RPM then the motor studders and seems to hit a brick wall.
So, am I off a tooth and blind?

Is it related to the car sitting for a few weeks? I don't drive this car much. (bad gas?)

Anyone else have this prob???

I'll look again at it in the daylight.

Thanks in advance

 

Sounds like maybe a skipped tooth?

Have you checked the ignition timing?

 

Would this really matter? I didn't move the dizzy at all. The spark timing was set correctly before the timing belt install.

Edit: Oh after thinking about this further... the ignition timing should be all messed up if it has skipped a tooth... riiight.. thanks.. i will check after work..

You know you have to set the timing after belt install, right?

Right, easy way to tell if the belt is off. One tooth usually equals about 14-18 degrees.

 

even if it did not skip a tooth timing could be all messed up.Remember that when you put the new timing belt is not stretched like the old one and cam timing is never exatly like it was before.

It's not likely to be off that far.

 

Yeah This is always good, but provided the ignition timing was reasonable before even if its off a few degrees it wouldn't make the car run as crappy as it was.. I hear ya about the streching of the belt..

You got it right.. I was off a tooth I checked the ignition timing and it looked to be about 12-15 off.. I'm glad I didn't have to take all that crap off again to get the belt off the valvetrain pulley. Just undid the tensioner and was able to slip it off.

Chiovnidca, mmuller, LudeyKrus, Thanks for the info...

 

This sounds like what my wife's accord is doing after the timing belt change I just did. The car is a little shuddery and definitely there is a low end torque loss from 1K rpm to about 3K rpm. Then the car takes off. Some have recommended the timing belt is off one tooth. But I did not check the ignition timing after replacing the timing belt. So it looks like I am going to check the ignition timing first. Then I will worry about the timing belt if everything else checks out ok. Thanks everyone. This site has proven to be a great help!

 

I checked out the ignition timing this weekend and it checked out ok. So I pulled the top timing cover off, adjusted the belt one tooth on the camshaft sprocket (after locating TDC), and put it all back together. I took it for a test drive after and was like new. It's amazing how difference one tooth can make on the car's operation. Thanks to everyone for your help. I definitely learned alot about this car by doing the timing belt change myself. Thanks!!

 

Yo just check your timing again, it might be off a little!!
