Engine Performance problem
2000 Cadillac Deville V8 Front Wheel Drive Automatic 145000 miles
I filled my tank up and added Berrymans b12 in gas tank at that fill up. The temperature was 30 degrees or less for most of the day. I get a engine light, code was MAF, I replaced the old one keeping mind to ensure no air leaks when installing the new one. A day or two later weather is still in the low 30's or colder and I get a stutter in the enging, a slight one then smoothes out. I have Autoxray 6000 connected, I find a pending code of the p0101 MAF sensor, I later sprayed berrymans b12 carb and throttle body spray to check for leaks as it was idling, did not hear any rpm increase, I checked all air clamps to ensure they were tight. Checked the MAF conector to see if any pins were bent, none were bent, re connected it. Drivability now is more frequent with the hessitation sometime around 42 mph and 62 mph, instead of once or twice I feel more 5 - 6 times one way. All this started when the weather got colder and after I added berrymans to the gas tank. I do not believe berrymans did anything as it is a additive, and GM was or is still using it themselves. Any ideas?
have the same problem?
