95 EX Vtec. Code 4 Please Help - Page 2

OK guys we did it once again. This problem is SOLVED. I bought a ECU from junk yard for $40. They give me good deal since I bought so many parts from them already. Plugged it in. CEL is gone revs perfect. VTEC kicks in. Pretty fast car I would say. My friend opened the ECU and said it had a bad resistor. This is rear for Hondas but who knew.


Thanks guys.
All of you are great.    The dealer told me all I needed was a "tune up" using OEM parts. I paid $100 for that diag. But it needed a new engine and ECU. I got to get my money back. lol

Cool, glad its fixed.  ECUs are pretty robust, so all the measuring was to rule out bad wiring which is actually more likely than a bad ECU.
