In my 90 ef hatch every since i got it the car "red lines" at 3500-4000 rpms. When the tac hits 35-4 the needle goes all the way to the end and starts to red line. What can i do to fix this??? and sometimes when im getting up to speed in 3ed or 4th the car kinda sputters like its not getting air or gas or something. or if it were getting flooded out.

My Gsr in my last Crx was doing that and it ended up being cylinder position sensor and cam sensor. Any Cel codes??

Dat EF Doe

I have not checked for codes. What did you do to fix it?

hondacrx0991

It ended up being a wiring problem to the ecu from the dizzy. It was to the point where I would be driving and it wouldnt go past 3500-4k (limp mode). I pulled the cel code 9 which is cyl position sensor. After that was fixed and the code was cleared it ran great. My friends srt-4 had the same problem and it ended up being the cam sensor. Also check your tps. Check the cel code and go from there. your running obd-0 right ?

Dat EF Doe

Yes obd0 but will it even give me a code? if my check engine light isnt even on lol?

hondacrx0991

oh yeah the light has to be on. Thats extremely odd if its acting like its in limp mode but there's no cel. Have you checked your tps to make sure its calibrated correctly and functional.

I have not checked my tps...

I would do a little more trouble shooting to figure out what exactly is wrong with it. It sounds like a distributor problem to me. Check to make sure the map and tps plugs aren't switched, check to see if your running any codes and see if you can have your distributor tested before you go out and spend $ on parts.

I just checked the code and on the ECU the light blinked once i don't know if thats normal but i looked it up and that's the Oxygen sensor. Cant that be the problem?

hondacrx0991

Was it a short fast blink or a longer blink. I know it sounds stupid but its two different codes.

Dat EF Doe

lol, it was just a short blink. just one short blink once i turned the ignition on.

hondacrx0991

Its a heated sensor so the engine has to be running.

Dat EF Doe

So that code does not even matter?

hondacrx0991

the one blink is normal when the ignition is turned on. The thing that gets me is how your not going past 3500-4k and no cel what so ever

Dat EF Doe

its changed out of no where lol... its like 4 in 1st and like 5 in second. it just changes randomly. lol. but its before 5 everytime...

and in third you can hear how its kinda cutting out...
