Help! My R33 wont go!

[PJ]

Today I finished putting back all the bits after changing an exhaust manifold. Went for an initial test drive for about 10 minutes and everything was fine. Came back, left the car running and went to go to the bank, about 30 seconds into the trip I changed from 1st to 2nd manually (is auto) at about 4k revs when it sorta coughed then kept going. It kept on getting worse and was trying to stall, got about another 100m when it finally did. Tried to restart but was coughing and would stall again, tried to limp for a bit but no good. Switched it off and on again, same thing. Checked under the bonnet to make sure everything was still where it should be, reset the ECU then tried again, no good. Holding the throttle steady it still cuts and jumps up and down the tacho. Battery voltage 12.5volts, 3/4 tank of fuel, replaced fuel filter about 12k ago, replaced spark plugs about 1.5k.

The car is a 95 series 1 r33 gts25t auto.

Any help or suggestions will help, the car is stranded!

damaged / broken air filter meter perhaps? try borrowing someone else's working air filter from another r33. i think the r33's go into limp mode (wont rev above 2500) when the afm can't sense airflow properly. failing that could be the auto box is on the way out and it was just a conincidence that it occcured now? i'd try another afm first

hope this helps

It revs above 2500, don't really have anyone with an r33 that I could test it with (am in geelong). Thinking maybe fuel pump, or tps or something weird.

Will have another look at the afm plug and make sure its making a connection.

Thanks for the speedy reply.

check the pulg & try to clear the hot wire w/ some contact cleaner

Thanks for the tips but looking closely with a torch, it was one of the pipex coming off the intercooler that popped off. So glad it wasn't something serious, its bin a long day. I lost the GT badge I just bought :-( along with all the other mechanical troubles....
