ecu codes?
Sent to Car Experts April 11 06:41 PM

i have a 1994 nissan altima se. I scanned the ecu and it comes up with 21 and 34 codes. The 21 is ignition signal and the 34 is knock sensor. The KS has been out for 2 years with no woes. But this ignition signal is causing my car havoc. The more throttle that is applied the more it bogs. It has all new tune up parts and no vaccume leaks also. The only thing the haynes manual says about this is "see dealer", i really dont have the money for that! Can you guys tell me what exactyl this code is saying needs replacing?
