Car -
AE86
motor / part in question -
4AGE 16v
problem -
Problem is the car is difficult to start, but thats because i have no cold start set up (motor had itb's on it so its all cut out, has standard manifold on for rwc)
When its started it will idle fine, however when you rev it it will bog down, backfire then struggle to rev up. The motor has been run by this ecu and have tested with another, which changed nothing.
It will rev fine if you only give it a small amount of throttle, but as soon as you give it a little too much it bogs down and backfires, then revs up.
I have tested tps, and just in case my multimeter was dodgy ive tried running it without it, all with the exact same results.
The fuel pump is operating at 40-45psi which ill put down to the cheap gauge i was using to test it, fuel pump jumps up to 100psi when the return line is blocked, so it seems the fuel pump is fine.
I have checked that the dizzy is getting spark from the coil, and that the dizzy is giving power back out to the plugs, all seems to check out
I tried adjusting the timing but bridging t and e01 didnt seem to change my timing at all, so i left it around the 15 btdc mark (Diagnostics mode was turned on as I got a code for the O2 sensor (or lack of))
Ive got another map sensor here but it uses a different plug and was hoping that i could avoid chopping plugs on and off things.
occurs/started when -
All the time! :verysad: This is the first this engine has run in this SHELL!
I got a video of it here~ http://www.ae86drivingclub.com.au/dcimages/5/0/4/5/516026.jpg (http://i57.photobucket.com/albums/g236/blade_059/IMG_5560_zps0ae1b6bc.mp4)
