Need Help With My R32 Gtst

[scotti-boi]

On the recent long weekend me and my mrs went to canberra to get away, anyway as i enteredt canberra on the friday nite my 32 started to misfire and was acting up something servere.

Anyways the next morning i went out of the motel started it up and it was fine... We went out and as i started it a couple hours later it started to play up again on the way up to telstra tower.

Anyways after towing it to a mechanic he said it seemed to be something to do with the ecu because he cleared a ignition error on the ecu. Which turned out to be bullshit because it started doing it again afrter towing it back up to sydney.

So far i have been trying everything i can think of, i have changed spark plugs, coilpacks, ignitor, and even got my hands on a stock unchipped ecu to see if it would cler the problem but seems not to be.

What its doing is popping and carrying on between 2500rpm and it wont rev over 5500rpm. It pops sounds like its on limiter and it backfires.

Another member of the forum seems to think its the cam angle sensor? Could this very well be the problem? Also when it tries starting it will want to kick over but then starts mucking up like cutting in and out but its hard to explain exactly over the net...

Let me know guys i need it running asap.

it sounds like you have changed everything.. its a long shot but could your timing belt have jumped a tooth, i dont see how the CAS would cause suck missfiring etc.. would just advance or retard the timing if it has slipped. it might be shot though..

also put a cupful of metho in the tank to get rid of water in the fuel. that could be your problem?

loom might be stuffed?

apart from that im stumped as you seem to have checked all the obvious ones

if you do figure it out let us all know what it ended up being.

See if you can get a consult cable hooked up to a laptop to log AFM voltages. The wiring could be dodgy and dropping voltage at times.

I am very interested in this too as the same sorta thing is happening to my gtr (topic: Really really bad idle R33 GTR).

Let me know how you get along...

Do a cold and hot compression test. Clean your plugs and when it misfires check them
