'92 740 Turbo w/ Gas Soaked Spark Plugs 700 1992

You can just unplug the suppression relay to clean off the plugs; it is what supplies the signal for them to work. Typical problems when a car is running full-a rich is the coolant temp sensor, the air mass meter, the fuel pressure regulator, the fuel computer, or the wiring harness. On a turbo, you can add any of the numerous intercooler hoses. The car is really too young for the problem to be the wiring harness, and besides Margaret Thatcher threw Lucas to the winds in 1989. No more government contracts meant they had to make a quality product. We shouldn't see the problems with the wiring harnesses like we did in the past. If you have had a coolant leak in the past few months to the point your car knew about it, opt for the coolant temp sensor. Pull the vacuum line off of the fuel pressure regulator; if it is wet or smells WAY too much like fuel, this is most likely the problem. If it's the air mass meter, you should have a code for it. Lastly, check all of your intercooler hoses for a hole. Hope this helps.
