Hey Scotty, love the channel. I have an 01 corolla with 137k miles and just recently it started to feel like it cuts out fuel while driving. It's does it very intermittently and can be a week or 2 before it will do it again. And then drives fine. Code p0171 one is on and so I changed the bank 1 sensor. Also I cleaned the maf sensor, I used a screw driver to listen to he injectors and all seem to be ticking at the same intervals. I also unplugged the maf sensor while the car was running and the car stalled leading me to believe that it's not the maf. Also I did the same with the coils and each time I unplugged the coil the car stalled which I believe would mean that the coils are ok. When I first start the engine I did spray carb cleaner around the intake manifold gasket and it raised the idle so I'm assuming I have a little bit of a leak there (not sure if that could be causing the intermittent sputters). When the engine is warmed up and I spray the carb cleaner the engines idle doesn't increase but I'm thinking possible the carb cleaner is evaporating before it can get sucked in. Also I do have a bad exhaust leak on the e gaudy manifold flange (where the cars exhaust meets up to the manifold) not where the manifold meets up to the engine. Any insight or ideas would be greatly appreciated. Thank you for your time.
