Accelaration Issues..Please help :-(

[mrgylex]

I have a 2001 porsche boxster S- with 76K miles- at first I got codes p1128 and p1130...I went to the dealership and they told me that the MAF could be bad..I said no problem, so I went and purchased a brand new one and replaced it...the car worked great for about 3 days then I got a serious drop in acceleration in all gears, I'll press the gas pedal down all the way and it will only speed up much later or when the pedal is on the floor as well there is louder ticking sounds in the engine bay and the exhaust note is much louder it sounds bad. The new codes that come up now are p0442 and p0430( leak in the evap) & (cat efficiency below thresh hold) I cleared the codes and same ones came up again. I would assume its the MAF , but the code no longer comes up...what can it be..I am so lost..I will be taking it to the dealership if no solution is possible. Can an evap leak or bad cat cause all these issues? I have an actron so if anyone wants graph print outs or sensor values..please let me know. Thanks!!

well...noone has replied so I decided to take the car to the dealership...after all the trouble of doing my own diagnostics it ended up being that the gas cap O-ring was severly rotted out and letting gasses into the evap system so that caused the loss of acceleration. As well some hose fittings were changed to tighter ones as they lost the tight seal they originally had. I still have the cat effeciency code..guessing its genuinely a cat issue and need to replace it.

Ive researched this site for days looking for awnsers...ultimateley did not help the dealership found the problem 3 hours in...gas cap with bad O-ring , although i still have a very very small engine hesitation now..still much better....more headaches to eventually deal with .

I knew that, that's how I found this thread in the first place.:rolleyes: I meant how do I find my own old threads? When I click on my profile it only showed 3 of my threads, I'm pretty sure I had many more.

Thanks
