| Hi all, My previous message from almost a year ago was locked so I wanted to post the original and follow up message: As I was driving back yesterday, I found that my car lost power all of the sudden as if the ignition failed. The car would surge forward and then lose power, then after a few seconds surge forward again. If it's the PTU, it is intermittently coming on and then off. The engine UNDER LOAD doesn't seem to want to go over 2.5K RPM, and at times feels like as if it is hitting the rev limiter, causing the engine to lose power for 1/3sec at a time when trying to go beyond 2.5K RPM (but this doesn't explain the other scenario). The car would eventually lose all power and not idle where I would have to crank the engine multiple time to get going. It was a horrible hobble back home :( It turns out it was the MAF sensor. I am guessing it caused two issues: 1) the failure of the MAF prevented the engine from running properly altogether. This made is really difficult to keep the engine running for any period of time. Often, the car refused to start after some driving. 2) keeping the car under 2.5K was also difficult to do for the rev happy Z. When all this happened I did not expect the MAF to behave this erratically. Also, before the MAF failure I cleaned it well with CRC MAF cleaner. I am certain that shortened the life of the MAF at this point. After I replaced the sensor courtesy of Specialty-Z, I was up and running with no issues. Thank you all for helping me through this issue.
