heres a quik explanation of my .... The car was running with a 88-89 PG7 ecm, and wouldnt pass emissions, so I decided to try out the Si Ecu to lean it out, but when the Si ecm went in the engine light turned on after the motor warms up, a Mechanic say its the cam angle sensor thats throwing a code. but it turns back off when the PG7 is put in, except for yesterday i was mobbing with Si and it was running horribly so I put back the Pg7 and now the engine light wont turn off =\

I beleive my motors a 87 integra motor, not a true ZC.. oh yea wondering how do i check the check engine light to see if theres anything else wrong with it

*the ecu Blinks 9 time*

 

there is a see thru window on the ecu .when you turn the key to the first position it should blink once and you count the number of blinks after that and it will tell you why the check engine light is coming on.

 

yea it blinks 9 times, think its the cam angle sensor...

 

anyone run into this problem before ?
