i have a D15B vtec. my check engine light is on. my vtec doesn't work and my idle now is around 1250 and it doesn't drop. when i turn my car off it it goes away and the idle is fine but it eventually come back on. what could i use to check the code. and can i buy the jumper to check my code. oh yeah i have a 91 si converted to obd-1.

 

well, you could always try to take the car to any shop and ask them to run it through an emissions test i think, im not too sure though. I'm running OBD0 for right now, and i was running OBD0 on my b16a, so i always had the little LED light on my ECU. But i think if you take it to a shop, and tell them your car is throwing check engine, they'll run a test and they should be able to tell you why, just a thought...

 

if your car is converted to OBD1 then you shoud have a jumper harness take the black and yellow wires on that bad boy connect em and read the code

Yeah on the obd1 conversion harnesses I've seen you jump wires at the ecu and it will make the cel in the dash blink...

How was your car converted?

 

thanks. i did all that and figured out the problem. it was blinking 6 times and it was my coolant sending unit . when i checked i saw it was my plug. the wires were old as **** so i just got a new plug cut the wires and soldered the new one on. everyhting is fine now.
