    The MAP test point should read at least 7V with the engine not started. Getting that replacement ECU might solve the problem. Then you can get the first one fixed as backup. Bruce Roe

    You ought to try bcroe@juno.com . I might finally have figured out how that Cad in box works. I could send a MAP sensor, but its a worry that it won't get installed properly, or here could be additional problems. I like to completely check the ECU on my tester. How come you changed your mind about the NAPA ECU? Bruce

    I rather send you my ecu and you do the job, I will email you today!

    I think napa is charging way too much for those, let's not forget that they also charge a extra $84 for core.

    And I can't purchase online, I would have to wait until november and go personaly to a store.

    Ok, problem FIXED...

    Turns out that, no problem in the vacuum lines, no problem in the timing chain or sprokes...

    Bruce Roe was dang right!

    Problem was only the ECU, i sent him the module, 10 days later i receive it back, just plug it and voila!!! Everything worked as is supposed to work.

    Bruce Thanks very much!!! was the best spent money ever!

    This guy is good!!!

    cheers bruce!
