    Default all the problems of a 4age,

    after some help iv had my 4age up and running for a few months but now i have done a few things like
    replace cam seals,
    replace the front crankshaft seals,
    allloy rad,
    timing belt,

    now there has been a few problems with it i have go it running again and it runs good and all timed,

    but some times when you start it will run crap and when you go rev it it won't rev like the tPS isn't working
    and when you unplug the tps it doesnt change it wont rev it will just be gayy,
    but then when i unplug the ecu and start it again it runs fine,

    im so frustrated with it,

    has anyone had this problem before

    I'm think the TPS is stuffed

    Leaking caps in the ecu, does it go into diagnostic mode?

    I am not to sure how to check if it goes into diagnostic mode,
    but i checked to see the the map was working its all good,
    but
    i don't have enough vacuum,
    cause i have to have the brake line hose off for it to start,
    " when the first dude tuned it he tuned it with out TVIS plugged in "

    so i was just going to have the throttle stop wind out a little bit
    and put a new TPS on it to see if that helps

    also the bottom of the throttle body had a few vac leaks so i made a plate to block it off
