    Your Car is doing exactly what mine was doing. Its the Torque Converter! I went mad trying to work it out. The Porsche Mechanic was stumped trying to work it out. We pressure tested the engine and fixed leaks, but the problem remained. Did all the code tests but not faults came up. Had the transmission removed and tested - All good. Like your car, putting my foot down and driving hard - the car would feel fine. It changes gears well. Its just cruising that was the issue. Ended up replacing the torque converter and the problem was solved. My car was at the mechanic for 6 weeks. Very frustrating!

    Thanks for your help, it was a failing torque converter that caused the problems. This issue does not show any fault codes so very tricky to diagnose apparently. Get the car back tomorrow....5 weeks later

    The diagnotic tools report no fault codes. Thats why mechanic is resorting to tuning issues but cannot find any. I am taking to Porsche Melbourne (aurthorsied Porsche dealers) Tuesday, I just want the stupid thing fixed. Do you mind if I ask what tool he used to check the car? I am not exactly sure. He just said his diagnostic equipment did not report any codes, in fact he said it was the first thing he did when he got the car. On one occasion, he road tested the car while in was plugged into a computer of sorts of some tool that reads the cars information while driving. He said there seemed to be a misfire and checked the spark plugs and coils but that did not fix the issue.

    Try unplugging the MAF and driving. Why do you think we should do this? I had a MAF sensor put in in Feb, when the car starting playing up it was the first thing I thought about. So i took it back to them and said I think the MAF is faulty. The installed a brand new one and it made no difference. They did not charge me for this.

    Thanks for the replies guys. The car is at porsche specialist and they have checked oxygen sensors and they are all good. The tyres should not be the issue as they have been on the car since the start. they are 285/? turbo style 18 inch wheels Car has fairly new idle valve. More ideas? It may be transmission related, seems engine is ticking all the boxes.

    Hey Guys, I have a 1999 996 3.4lt C2 Tip Cabriolet. It has been in the Porsche workshop for 3 weeks now entering the 4th week. My mechanic has tried many things without luck, so I come to you for help. The issue is, when driving along and keeping at a specific speed, the revs will constantly surge up then down. It does not do this under accellaration but only when you sit at a speed and keep the throttle constant to stay at a speed, for example 60 km/h or 100 km/h. We thought the 80,000 km major service would fix this but it didn't. New spark plugs did not change anything. Spark plug coils were check and no issue found. It already had new MAF Sensor in Jan but we replaced this again to be sure and the issue remains. Engine was checked for leaks including vacuum lines etc using smoke machine and no issues found. Transmission was serviced in Jan, oil changed. He has also checked the oil again and cannot see any issues. It may be the transmission but he doesn't think is so due to the above and also that this surge can occur in any gear. We are out of ideas, and I am losing patience, if anyone has any suggestions that would be great.
