we need more information about the car. . . .what engine. . . . is it swapped.. . w3hat ecu is in it???

are there any codes showing???

limp in mode of the ecu will make the car redline out at 3000 clear the codes and see what happens. . . then check for new codes and post what you find. . .

is a D16.. and the only codes that show are code 4 and 9.. they told me to replace the distributor.. and i did and is still same problem.. but another guy told me it could be the wires.. wha ya think?

Sorry to be such a noob but where do you see these codes? Like would they be under the speedometer and such? Or is there a way to check the ECU? I know nothing about ECU's and would like to know how to check and modify them...

On OBD0 ECUs (stock for CRXs), pull back the carpet on the passenger side floor and you can see an LED blinking through the cover plate. For OBD1, you have to jump the SCS connector that you use for timing the car and the check engine light will flash.

I didn't think OBD0 had a limp mode...

Check your battery connections. My positive wire came loose off the battery and was barely touching and it would cut out at 3000 RPMs.

thanx everybody bt i found the real problem today.. was two cables were cut off from the distributor to the computer.. the car runs perfect now..

 

[rex2nr]

that'll do it.... :shock: were they unplugged or actually cut?

 

[J's_90CRX_Si]

they were cut off.. the dumb guy who had it b4 me put a civic distributor and cut off the two extra wires completely.. he probably thought he didnt need it... so i had to buy the right distributor and pay a mechanic to re wire it..
