I am going crazy with Boxster

The latest Boxster Rebellion was an erratic, jerky ride. Then a loud "pop" and the ride ran smooth again. Checked code and there were none. What is going on here?
I am in the process of moving and I am stressed already. I don't need this uncertainty.

The easiest way to prevent a two page guessing game would be to use the obd2 port and see what the code is.

Chef,

You could save some time on this forum by putting your car info to your signature, model, year, milage, mods.

Why worry? Run it until it breaks or there is a repeatable problem then get it fixed. No worries.

This idea is really only practical if you are going to drive within a few miles of your house. Who wants to be on a country back road, dead with a celly because you ignored the warning signs of a deeper issue..

I vote bad MAF.

I once (after numerous months) tracked some issues I had down to a bad MAF. On occasion it would cause my car to take fits like erratic power delivery and at times didn't even want to pull out from a stand-still without majorly riding the clutch, then it would pickup suddenly and just take off with accompanying popping like it was backfiring thru the intake, or pull strong up to 5k rpm then go flat in the powerband and not want to pull thru it.

Never got one CEL or code. Ended up changing it and everything was better (for awhile)...even if you have changed this recently don't rule it out, as later I found out that the "new" MAF I had in put several months before was causing my car to run extremely rich so I had to get yet another one which cleared up that problem.

Do a search on the forums for testing your MAF. I think you have to unplug it and drive the car around some but then my memory fails to recall what the rest of procedure is or the difference in having it unplugged tells you...maybe someone that knows will chime in.

Good Luck with it...having had an issue that I couldn't track down was quite disheartening so I can somewhat relate.

Smile I think I know what the problem is

I've discovered that the erratic behavior is related to low fuel levels. When the red light is on the fuel guage the behaviour begins. So solution is to not yet very low on fuel.
