have a read of this, it should alow you to acuratly find out exactly what code the ecu is producing mate.
i went to a mechanic and he said its a code 2, whats a code 2?
damn, its kinda confusing aye, as im a noob to engine problem.
when diagnostic test was done. light flashed 2 times then stops then flashes 2 times and repeats itself. when i drive it, idle goes up n down from 1,500 to 2,00 rpm. and max revs is about 4000-5000rpm.
Even with TVIS inop the motor will still run past 4000 rpm.
Could be a code 22 - water temp sensor? although the symptoms you describe aren't synonymous with the symptoms of a bung water temp sensor.....
In what way is it not revving past 4000? straight cut out, starts misfiring? etc?
You can have any brew you want... as long as it's a Datsun / Corolla / What is that?
starts missing, popping noise
My guess, your engine is not getting enough fuel.
I thought that before you mentioned that it starts popping.
Check the washers around your pulsation damper (inlet to the fuel rail) are orientated correctly. I ditched mine in the end, it was temperamental; sometimes it would not flow properly, pending its orientation (I ground off the stopper so I could spin the damper fitting around so my fuel line cleared my throttles).
The only factory ae82 bigport engine I have here doesn't have one anyway, so not sure why jdm bigport rails have them.
with my ecu im getting a code 2 ( flash 1.5s pause flash 4.5s pause then repeats) with another jdm ecu im getting a code 1 ( flash 4.5s pause then repeats. )
does code one mean its working fine?
with the code 1 i then took out the STOP fuse at drivers kick panel for 10+ seconds and put it back it, still same problem.
but when wire is still connected to T and E1 on code one and i start it and runs fine, but engine light flashes (keeping in mind that the T and E1 and still connnected
code 1 is fine its normall. When you have it bridge it will show code 1 if theres no problems. You have found your ecu is giving you a code 2 error but another ecu is saying its fine code 1 "normal" Try to put your ecu back into your car and pull the stop fuse out again this will rest the codes already in memory. You gotta rest code faults after you fix them otherwise you wont no its fixed
The ecu must see certain parameters before it logs a fault code, which i guess that if the test ECU didn't fix your problem, it didn't see those parameters yet.
From your description i'm beginning to think your problem is ignition related... poor coil grounding maybe? did you change the coils over from car to car with the engine?

Well if it did not stall, then you have a map sensor fault and ecu is using a base map to keep the car running. 4agze map sensor wont work, its for pressure not vac.
Check your actual engine wiring harness and make sure on of the map sensor pins has not dislodged. This happened to me and engine ran exactly like yours, misses at idle/partial throttle/at 4000rpm, not reving past 4000rpm.
