wheezy Posted April 22, 2010 Report Share Posted April 22, 2010 The engine will not rev above ~4.75k. I checked the spark plug wires and they seemed fine. I replaced the spark plugs and that did not make a difference. Should I replace the fuel filter? Is there anything easy I'm missing? Fuel injectors? Distributor? Since its not revving high does that mean something is on its way to failing and leaving me stranded on the road or is it fine to leave it alone since I never rev it that high anyway. Its the 1.5l sohc. Quote Link to comment Share on other sites More sharing options...
CRed05 Posted April 22, 2010 Report Share Posted April 22, 2010 Automatic? Does it happen when you drive it or just when your sitting in park? Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted April 22, 2010 Report Share Posted April 22, 2010 Do you have a Check Engine Light on? Odds are you do and the car is in "limp mode" that will not allow the motor to see 5k rpms. If you do not then check your distributor cause its prob going to take a shit on you, itll either be the coil or the ignitor that go bad. What year civic is this as I might have a distributor laying around Quote Link to comment Share on other sites More sharing options...

ansonivan Posted April 22, 2010 Report Share Posted April 22, 2010 - plugged cat - check by removing the o2 sensor to check for an improvement in revability - timing belt slipped Quote Link to comment Share on other sites More sharing options...
wheezy Posted April 22, 2010 Author Report Share Posted April 22, 2010 (edited) - plugged cat - check by removing the o2 sensor to check for an improvement in revability - timing belt slipped so is this a good thing to try? How would I know if the timing belt had slipped? It runs fine up till ~4.5k in neutral, seems like it went a little higher in gear. Heres a video. It really sounds like shit above 3k. http://s22.photobucket.com/albums/b338/wheezytoo/?action=view¤t=P4220151.flv Its a cx and all stock except for a cold air intake as far as I know.

wheezy Posted April 22, 2010 Author Report Share Posted April 22, 2010 Power delivery is normal up to the newly lowered rev limit? I don't know what the normal power is since I just got this car but it seems alright. I guess Ill rev the shit out of stuff I'm gonna buy in the future.

Richard Cranium Posted April 23, 2010 Report Share Posted April 23, 2010 200 shot of Nawsss. That'll fix it right up. She'll rev like crazy.... for about a second. Quote Link to comment Share on other sites More sharing options...
Ef8sirJunkie Posted April 23, 2010 Report Share Posted April 23, 2010 watched the video that looks like a 2 step (launch control). when driving over say 6mph does it rev past that? you also notice the cel is not on. take your ecu out and open it and take a picture please.

CbusBusa Posted April 23, 2010 Report Share Posted April 23, 2010 Even with low oil pressure (when the car is cold) it will rev high, but the vtec solenoid won't engage the secondary cam lobe and you won't gain the vhax powa, so you fail and teh funny. my brother's car did the same thing and it turned out to be the vtec solenoid.

wheezy Posted April 23, 2010 Author Report Share Posted April 23, 2010 (edited) lol so maybe it only does rev to 4.5k from wiki: Power : 70 hp (52.2 kW, 71.0 ps) @ 4500 rpm wouldn't max power be fairly close to the top rpm edit: after searching google it looks like the redline should be 5500 or 6500.

DaddyBuiltRacing Posted April 23, 2010 Report Share Posted April 23, 2010 Redline is 6500 on the cx, your saying the problem happens at 4500, that leaves 2k rpms til you should be seeing redline and honestly about 2200 before you hit fuel cut. I still say the issue lies within the dizzy Quote Link to comment Share on other sites More sharing options...
wheezy Posted April 23, 2010 Author Report Share Posted April 23, 2010 in gear it revs to 5k I decided to replace the fuel filter since it had probably had never been done and there was a small chance it was causing the problem. It didn't change anything and now at idle it bounces back and forth between 800-1000 before it settles down. ffffffuuuuuuuuu I guess Im just gonna take it to gearheadz. fucking bought this thing to take on a 5k mile roadtrip since it gets 40mpg and now I'm spending as much fixing problems I didn't know it had as I would have spent in gas just driving my truck. This sucks. Quote Link to comment Share on other sites More sharing options...
