Hi,

Hope someone can help with this one. Did a search but nothing useful came up.

My Civic has had a flat spot for a while now but recently it's got worse. So far, I've replaced the cap, rotor arm, leads, plugs, fuel filter but no change.

Went to check the timing and came across an issue. I'd marked the center groove on the crank pulley with white paint to get a better view when reading, connected the timing light up and went to check but no matter how far i rotate the dizzy, i can't seem to get the marking anywhere near the arrow on the plastics.

The closest i can get it to it is when i rotate the top of the dizzy body towards the bulkhead but it's still about a 1/4 inch off. The car doesn't drive better either. Keeping the revs low it hesitates and misses slightly.

Any ideas?

Car is a Civic EG6 with B18
Chipped ECU

 

Anyone?

 

re check your belt timing. sounds like one of your cames (most likely your intake cam since it wont line up) has skipped a tooth or the belt was installed wrong.

 

Like DCRB said, check the cam timing, but if not that, maybe you have the spark plug wires all one spot ahead and the distributor turned all the way the other way so it barely runs???

 

The car runs fine and has done for years. The flat spot has just got a bit worse recently and it's annoying me more so want to cure it.

Not sure what you mean by the plug wires being one spot ahead?

 

Mechanical timing is off a little. I had the same problem.

 

Thanks!
