I have an Australian Excel, 1998, manual, 1.5L DOHC, 150,000km.
For a while now it has a miss on acceleration, clears up above 1800~2000
Checked the engine codes 4444 (all clear). (Pre OBD2)
Had new plugs fitted, and the injectors serviced, made no difference.
Checked the coil pack resistance, manual says should be ~500 ohms for twin
cam or ~.5 ohms for single cam. Mine actually measures 1 ohm. My wife has a
similar model so checked the coil in that, measures same as mine, hers runs
What could cause this problem and not show up as an ECU code?
