    reading codes

    The light doesn't flash. It stays on constant... The engine pulsates but only when the break is applied. It's REAL annoying at stop lights!

    reading codes

    I figured it out... I think. I can't read codes because there arnt any there... I think the spark advance was so retarded that it wasnt running correctly. I advanced the distributor and the truck moves out pretty well now... the engine light doesn't come on until I floor the throttle now. The...

    reading codes

    I've been using the one on the passenger side. I didn't notice any other connector but I'll take a look and give it a try. Last time I read codes I didn't mess with the connector and it read code fine...

    reading codes

    Wow,that was just like reading the book, lol. Do you have mitchel ondemand or something? I need to know why I can't get codes providing I've done everything above.... The light does not flash, it just stays on as if the jumper wire is not there. I've tried pushing up on the wires but I can't...

    reading codes

    1988 toyota V6 pickup I need to read my codes. I know where to jump, I've done it before but this time I get no response. The computer has a code while running but when I shut it off and jump the terminals, the check engine light doesn't blink- it just stays light. What could be the problem?

    I'm looking for a brand new computer harness for my 1988 Toyota pick up. Would anyone know where to find one besides toyota? Aftermarket maybe?

    running without a knock sensor???

    Ya, everytime I take the motor apart I pull off the battery cable... I am now thinking about pulling the knock sensr out of the harness, providing there ar eno sufficient visual defects, wrapping it in electrical tape and putting it in its own plastic protector... That will eliminate ouside...

    running without a knock sensor???

    I'm oging to run my own coax line from the KS to the ECU... I htink maybe the shield on the coax in the harness may be lettign EMI through. It might be cracked but the thing is, if it's cracked it could still test good on continuity... but let EMI interfere with the signal form the KS...

    running without a knock sensor???

    Ok... I took out the knock sensor. Remember, I swapped this sensor with another from another truck- then got a code... Even though the sensor was known good, it had a different part number (now I look). If I put in the wrong part from the start adn chased all these problems around I'm going to...

    running without a knock sensor???

    I think I found the problem with the pulsation... It was "cutting" out... the coil wire was loose... still have the code 52 though....

    running without a knock sensor???

    When it's idling it'll keep cutting out like it wants to stall but only for realy brief cuts. Time in between cuts would be 1/4 of a second to 2 seconds. If teh throddle is cracked just a tiny bit it'll pulsate realy fast. If I push the throddle plate closed the time intrevals between the cuts...

    running without a knock sensor???

    update Ok.. the truck is together. It runs. It pulsates no matter what you do (the motor) one minute... then all of a sudden it will go away and run fine for a brief period... then pulsate again. I still get teh code 52...

    running without a knock sensor???

    Vane connector? I could have sworn I connected all vacuum lines but I'm open to suggestions... I swapped out the knock sensor with another used one... maybe I should just spring fo rht enew one.... (its like $200!!!) and go from there...

    running without a knock sensor???

    arrrggggg!!! So I put the toyota all back together (I swapped the harness incase I had a short in the line from the Knock sensor) Well, now the thing wont start... I turn the key and it sputters and then stalls like its got no fuel pressure.... Almost sounds as if the timing is off... Anyone?

    running without a knock sensor???

    running without a knock sensor? I cant get my knock sensor to give a reading to the ECU. Short of running another cable from the knock sensor to the ECU.... I want to disconnect the sensor. That being said... the knock sensor retards the timing when there is a short or open circuit... I read 5...
