Probleming I am having is sometimes the engine idles fine then it just loses rpms, engine stumbles, some times stalls out. Do notice a smell like I'm burning racing fuel. Possably running rich. I only run 87 octane gas. I took it to a garage and had it hooked up to a monitor, O2 sensor was showing low voltage and MAF sensor voltage readings where all over the place. Replaced both, still same problems. It already has a new fuel pump, filter and ERG valve on it. I did the resistance and voltage test on the coolant sensor and they hwere with in specs. Went over all the vaccum lines and they are ok. Running out of options. Any ideas?
