Oopsy guys! My mistake, no need to wonder about the plug restrictor, I removed the 2nd ECU to my surprise there were two more where they weren't before! They must've popped off the actual plug itself and swapped themselves over. Duh! By the way Peter, forgot to mention earlier, another excellent preliminary prognosis!, I would've never have guessed it to be the ECU, and yes, just noticed the wiring attached to have been tampered with sometime in its life, using those plastic crimp wire taps. Will check them though.
The new ECU has just been checked with no visual faults, although while attempting to do "Test Mode Diagnostics" using E1 and TE1 pins, the malfunction indicator lamp doesn't appear to flash to show test mode. So presuming there may be a circuit fault, I grounded TE1(Green/Yel) output from the ECU plug to bypass any possible open wiring, even trying to multimeter the malfunction indicator output(Blue/Yel), and still nothing. This "Test Mode" worked before the coil changeover 2 months ago. I hear Miles Baker had a similar problem on this? Anyone know whether that was ever resolved?
Will recheck the Idle Speed Control Valve Mark, although it has been cleaned rigorously many times finishing with a blast of compressed air. Also hooked up a timing light yesterday, and the flashes seemed inconsistent off some of the leads but regular on the others. Timing mark on the balancer also seemed quite jumpy at idle(Up to 10degrees back in forth from one flash to another). So I'll try what you have noted too Mathew. So many possibilities for the same cause. Cheers on your input guys, I shall keep you all posted.
