[QUOTE="scott degroot, post: 978206, member: 66039"] I used the term "scan tool" generically. I wasn't aware that there was actually a company called Scan Tool...pretty good idea on their part. If just 1 bank is rich then chances are that the culprit is an injector. Other possibilities are the wiring to the injectors and I guess even a O2 sensor could casue it. If both banks are rich you could be looking at injector wiring, injectors(highly unlikely that 1 injector on either side of the engine would fail at the same time though) a faulty MAF (usually fails lean though) high fuel pressure, ruptured fuel pressre regulator, an air filter so restricted that hurricane, force winds couldn't pass through it, plugged exhaust. These are just some ideas. These also assume that the engine is mechanically sound. [/QUOTE]
