First off, i have a 91 crx si with a dohc zc,this happened to me about last week as well, then went away until today when i got out of work....> i started my car cel comes up, so i start to drive, once i hit 3,000 rpm's it sounds like its hitting rev limit so i shift through all my gears to get to the right speed so i dont get pulled over for going too slow at 3,000 rpm's so i can get home. about 8 min of driving the cel goes away and im able to drive normal again. this is the second time this has happened to me in two weeks, i had the car for about 3 yrs now an drove it with no problems.....> mind you my pm7 ecu is chipped so rev limit is gone... anyone?

 

Here's an idea!

post the code

 

Yea men we need the code to help ya out it could be a couple reason why it does that we need more info...

 

Cel on dash stays lit yellow.. When I pull down the carpet to see the led on the ecu its the same as the dash it stay lit red... No blinking no nothing...

 

If the red led on the ecu stays on without going off at ALL it code 0 witch is bad ecu...

 

Yes that's exactly what it does... Thank you

 

bad ecu

 

anyone have a pm7 for me? lol

 

ok, so this morning i started my car NO cel now.....> drove the car all the way to work without a problem??? is it still the ecu?

 

Don't kno... Cheack all your grounds and power conections. Check fuses and make sure the battery terminlas are tight and corossion free. If the code does not come back problem solved. But if everything I mentioned checks out ok. And you still get the code try replacing ecu...

 

thanks i'll check it out today
