94 GSR performance issues
I'm been running my GSR motor in a 95 civic for about 10 years with no issues. It's been sitting a lot and only out a few times a year. Been driving it lately so I can sell it.
It hits the governor now at 7500 rpm where as before it was 8200.
The vtec sounds like it's engaging but it doesn't pull as hard as it used to thats for sure. I checked the solenoid and it clicks with 12v and did it running to hear if it was mechanically engaging. I hear something but I have nothing to compare it too to know if it's what it supposed to sound like. But i did some passes with it unplugged and it's noticeably slower.
I put new plugs in, didn't help, made sure there was no air in the coolant system. that fixed my high idle.
It idles a bit shaky, thinking valve adjustment (never been done) but I dont think that'll really help with the low revs and performance would it?
only mods on the car are mugen header, apexi cat exhaust, skunk2 intake manifold.
Any suggestions to check? maybe compression test? maybe vacuum leak? what else?
thanks
it has about 120k on the motor ecu is from the matching engine
