Firstly many thanks to Homer for sorting out my membership.
I have previously posted in the past, asking the odd question about Supra's and trying to source one for some time. Been looking for over 1 year but trying to hold out for one rather than having to bite the bullet and end up with a BMW M5/M3 Merc C32.
I purchased a fellow members 95' Uk Spura TT auto in April, noble chap, superb vehicle, spectacular history etc.
However, the car now has a misfire. Upon initial start up whilst the revs are closer to 2,000rpm, the car sounds/drives fine but then developed a misfire as the revs dropped. I got caught out on the road with this but after a couple of minutes the misfire cleared. However, now the misfire is always present and the car is now off the road.
I have changed the spark plugs to NGK iridium (prior to the misfire) as I was not sure when these were replaced and the car was much quicker and drove well (noticed an incorrect gap on the original plugs).
My local mechanic popped out to me, carried out a diagnostics (code read + data stream values). No fault codes are stored and no engine light is illumintaed.
Here is the data stream values;
Engine speed 925rpm
Injection Pulse Width 2.6 ms
Idle control 72 step
Air flow 0.72V
Intake Manifold Pressure 1 mmHg
Left Air/Fuel 2.6V
Right Air/Fuel 0.00V
Throttle Opening 0 Deg
Ignition Advanced Angle 10 Deg
Vehicle Speed 0 km/h
Coolant Temp Sensor 1V
L 02 Sensor Status LEAN
R 02 Sensor Status LEAN
L Open/Closed Loop CLOSED
R Open/Closed Loop OPEN
Knock Sensor NO
Start Switch OFF
Idle Switch ON
A/C Clutch OFF
P/N SW P-N-
Warm Start Enrich NO
Enrich After Starting NO
Myself and my mechanic are 99% certain its a coil breaking down, however he can't get out to me for 3 weeks to scope the fault with more hi-tech diagnostics equipment.
Can anyone help/advice so that I can get the car back on the road asap?
