2007 Targa 4 70000 miles

As I am going through the gears and accelerating fairly hard, my car has a dead spot at around 4200 rpms, as if it had a rev limiter and of course I use this as my Queue to change to a higher gear. I normally shift at lower rpms, but the times I have wanted to have a more spirited drive, it happens everytime.

I have fealth that since I got the car, but was not paying attention to the rpms and went by feel. The engine has that dead spot when I feel it could take a little more before upping gear. So I paid more attention and that is when I noticed the 4200 rpm thing.

Could this be a safety feature to avoid over revs???

 

You should not be feeling a dead spot at 4,200 rpm. What is the maintenance history? Vario-cam plus kicks in at about that rpm range, so you may have a bigger issue.

 

Secondly, who drives a 911 and shifts anywhere other than redline?

I don't have the service history. PPI was done by a very reputable shop in Mtl. Bigger issue like what??? I'll check itout further and see if it does it at every gear.

Real quick, I'd say it does it in 1st and second, maybe 3rd gear as for the other gears, I'd have to be on a track to find out 😎

 

Well initially, before paying attention to the rpms, my thoughts were.. geez, it sure reaches the red line quickly😁

 

When were the spark plugs last changed?

 

mine runs up to redline like its been stung by a bee ------------------------------------------------------------->


"I normally shift at lower RPM"... thats sad. The engine really starts to sing above 6k RPM.

 

I have no idea... as far as I know, they very well could be the originals. So far I have done all the fluids change and motor mounts. In the near futur, I want to do the spark plugs and coil packs, then the water pump, idler pulleys and belt.

 

I don’t have that issue in my 07 997.1 S. Revs strong all the way up to redline. Currently at 28k miles.

 

Load the free MyCarFax app on your smartphone. Then run your VIN and see what maintenance history is pulled. My guess is you have a fuel (fuel pump) or spark (plugs or coil pack) problem. If those can be rulled-out, then you have an issue with the vario-cam change-over.

For example, regardless of mileage, your plugs should have been changed in 2011, 2015, and again this year in 2019.

 

Carfax didn't show much, but I can check it again. Although no engine light is on, I have been feeling some burps and stumbles while idling and the rpm needle slightly moves at idle. But the engine pulls string with zero hesitation up to 4200rpm in lower gears.

 

The app I mentioned is different. Dealership maintenance should show up.

Your car's performance is NOT normal. In fact, all the fun starts at 4,200 rpm.

 

Thanks for that app, it shows things like tires were changed in 2009 along with maintenance performed. In 2017 coolant reservoir, front and rear shocks but nothing that relates to ignition or the likes.

Will consider the plugs and coils sooner than later.

 

I am the broken record for the forum on this but get all of your mileage and maintenance up to date - all of it. It makes problems less frequent and easier to diagnose when they do happen.

Not sure if the work has already been done? If there isn't a written record (typically receipts) then it has not been done. Oil, plugs, filters, belt, coils, drivetrain fluids, brake fluid, etc.

The smartest move is to buy the car conditionally after the seller brings the car up to date. If you need to push back offer to pay half of the costs. But good P cars and their owners are always up to date on both time and mileage.

 

I tested the Carfax app on my car. The mileage is off by 5000 and there are no service records. Even those I had done at a Porsche dealer are missing.
