Reply With QuoteDo you have a check engine light wired in? A low limiter sounds strange to me, even with a constant check engine light on my last car it didn't change.
16v 4age stock ECU rev limiter problem
1984 JDM MAP 4age out of an mr2 in my ADM sprinter
stock ECU
I've been driving my 86 around just fine for the last couple of weeks
went to give it to it today and it would hit a limiter at 5500rpm in every gear
i'm experiencing no other problems at all
running fine, idling fine
i went around checking all wires and earths were tight, all appeared normal
fuel supply appears to be fine, new lines, filter, pump is less than a year old
potentially a dead sensor? if so which ones would cause a limiter drop?
has it entered some kind of limp home mode?
i'll figure out how to get codes out of it as soon as i have time

I don't think its relevant to check engine fault cause that used to come up mid corners in my car and it never dropped the limiter
hooked up a makeshift check engine light
keeps throwing me 10
which is starter signal
so just take apart and make sure all the contacts and wires around the starter and such are okay?
it starts without a problem though
Start signal would only affect when it is cold and not reving cleanly etc... I'd be checking compression + timing next.

timing is fine
after a few misses and being able to push past the limiter once or twice by doing it gently, i was thinking maybe fuel supply, so i changed the pump and checked the lines
no dice
looking at maybe a faulty map sensor or a vacuum leak now
I would also like to know what causes this.
My car is doing the same, except I've got an Adaptronic on mine :|
Cam timing? Fuel supply at rpm? Buy a pocket scope and watch the injector signal, then the coil signal. Figure out what's not working.
Phirom, I have a pocket scope if you want to use it.
Cheers Ken! I was going to check all my vacuum lines this weekend and maybe see if I can record a log from the ECU to see what's going on.
all fixed
turns out it was any of these problems that i found:
leaking head gasket
worn out valves
cracked head
don't put dodgy engines in your cars kiddies
