Hey guys, so my 986 has become stuttery, and struggling to accelerate, I read a few bits online that said cleaning the throttle body and Mass Air Flow Sensor could help, so I removed the plenum and throttle body and gave them a good clean, also removed the MAF and gave that a clean with MAF cleaner, fitted everything back in place and started the car and unfortunately it now sounded like it was misfiring! 😬
I also read that you can run the car without the MAF connected and see if it improves, so I disconnected the MAF and drove around the block, the car didn't seem to struggle accelerating at all and definitely performed better!
So I ordered a new MAF sensor online, as I assumed that would hopefully fix the problem, the sensor arrived today and I fitted it in place in the engine/intake tube, took the car for a quick spin...and the problem is still there! 🤬
I'm now also now getting the fault codes P0300, P0301, P0302, and P0303...
Does anyone have any experience with similar issues and know a potential fix? Also any idea why it would seemingly run OK without the MAF?
Thanks! 🙏
