Hey everyone. Hope someone can help me out here. I have a 94 DX that has a bad hesitation problem. Once the engine warms up I have almost no power till I hit about 2k then it takes off fine. Cold seems to run better but still there. I have cleaned out my EGR ports. Got a new EGR Valve. Just finished a complete head job (and yes the timing is perfect). I am getting really frustrated. anyone have any ideas I am getting no CELs and not even an old code. I sometimes think I can hear a vacuum leak but I can never find it. Any ideas on what could cause this??

Thanks
Muddy

 

Probably clogged fuel injectors or bad plugs/wires.

 

Have you tried connecting a vacuum gauge? They're not very expensive and can tell you a lot about how your engine's running. Here's an article about using one to troubleshoot an Acura Vigor. Same stuff applies to Accords.
