I am running in my 91 DX a OBD-0 PW0 B16a and it runs fine but the last owner said the Check engine light was on because of the Knock Sensor. Well today I had the ECU Chipped to remove a few things plus Knock. Well I get home and Check engine light pops on and I see Code 16 Which is Injector so what the hell do I do to fix it?

 

Did you check your codes prior to chipping the ecu? If so, what code was it?
I would suggest to check your resistor box. Do you have an Ohm meter?

 

I took a look around the ecu and one of the wires were taped together so I fixed that and it went away. Then I went to drive it and code 17 popped up so I delete the code from the ECU chip and it wouldn't let me go into Vtec it would just bog out so I thru the code back on the chip and it only pops on if I get on it if I drive around fine nothing comes on lol.
