03 Civic (daily)
So... I have a 03 Civic ex with a 1.7 sohc
When I bought the car I found out it had a blown head gasket, so I replaced the gasket and the head (bought a head from Woodfin's, and had it rebuilt at a local machine shop w/ all new components)
Ever since I had that done, 90% of the time the car won't rev past 4000. It acts like it's bouncing off the rev limiter. The strange thing about it is that SOMETIMES...not often, but every now and then it will rev past 4k and act normal.
Anyone have any ideas why this could be? I heard something about the vtec sol could be bad? I know I had to buy and new gasket for that sol. when the original head/gasket work was being done.
Thanks.

VTEC solenoid problems won't prevent the engine from getting past 4k RPM. The only thing that will happen is that VTEC won't engage at the engagement RPM. The RPM will still climb, but power will start falling off. If the ECU is detecting a solenoid problem, and is limiting RPM, the ECU will also display a fault code for that. It won't do any fault actions without telling you about them.
You should have at least one fault code being displayed, unless the problem is purely mechanical like the distributor or timing belt aren't set correctly.
I always suspect human error if there are problems after an engine is rebuilt, or swapped, etc., because it's humans that do the work.

Re: 03 Civic (daily)
I dought that the issue is the distributor. I am sure that the 2001 and up civic's are distributor-less (might be wrong). It could be that the timing belt is off a little.
