My friend has a zc sohc turbo obd1 on a 88 crx. it wont pass 4k rpm and it throws code 6 and 10. after attempting to fix those codes it still shows cel. can someone tell me how to fix the codes and why its still in limp mode? thanks, anything helps.

 

Have you reset the ecu after "attempting" to fix the codes?

 

Yes i did reset the ecu

 

Does he have a vtec ZC? and did you wire up the CTS and IATS right?

 

check your wiring
