Gents,
Starting to pull my hair out here!
Despite all your help I cant get my truck to run without producing black smoke.
Not sure whats going on but I hope the following will enable us to get to the bottom of it:
Engine rpm = 700
coolant temp = 137f
Lambda 0.31 & 1.2 volts ****
engine map = 96kpa
manifold air temp = 69f
spark advance = 11.5 dbtdc
**** I know this value is incorrect, the sensor I fitted is a three wire with red, black & white cores as opposed to a black and 2 whites, could i have the wrong type of sensor?
Lambda besides even if i turn the required fuel down to 19 or so it's still running ultra rich!
Any ideas gents, getting to the stage where i wish id never bothered
thanks for your help,
mick.
