Well, I did the timing belt replacement on my wife's 1991 Accord DX. It was my first timing belt change ever. It was a challenge but I did it. Here is a question.

I started the car up after putting it back together. The engine idles smooth just like before I took everything apart. So I think the timing belt is just fine. However, when driving the car, there is a noticeable difference in acceleration and power. It was not a speed demon to begin with, but it feels pretty doggy from 1K rpm to 2.5K rpm. Do I need to check and adjust the ignition timing? Thanks.

you may have jumped a tooth when you put the belt on and the timing may have advanced or retarted

 

What kind of a challenge does this present? Can I just adjust the ignition timing to compensate or do I have to pull everything back apart and reinstall the belt? Everything was lined up correctly before I put it back together. And the engine seems to be revving and operating the same way as before. Just sluggish. Can adjusting ignition timing fix this?

 

I hate to be the bearer of bad news but it all has to come back off, if it is the timing belt the skipped a tooth. Get a timing gun and check the timing if the timing if off when you hold the revs steady that is your problem. adjusting the timing won't do anything that will just throw it out of whack more. The cam/ crank timing is off not the ignition timing so there is no quick fix.

 

After performing a timing belt change, does the ignition timing usually need to be checked/adjusted anyway? That is one thing I did not check.

If I do need to reposition the timing belt, couldn't I just remove the top timing cover (after removing the motor mount), rotate the crank to TDC, and check to see that the camshaft sprocket is at TDC as well? And if it is off one tooth, can I just loosen the tensioner nut, slide the timing belt off the cam sprocket only, turn it to TDC, put the belt back on, and apply tension? Then check to make sure that the camshaft sprocket and crankshaft are both at TDC?

 

yes you could do that just make sure that they ard both dead on with the tdc marks, and make sure when you put the belt on they dont move, this happens often just even the slightest variation from tdc can cause problems.my aim is japspecr34 if you have any more ?s just im me
