Help I need a speed/power check
- Thread starter Guest
- Start date
Primary distributor is driven from the crankshaft so if the engine starts and runs with the primary disabled, then the belt should be OK
I pulled each one off in turn, and as it ran on either one I did not get two hung up on which was the primary [
]How many miles has the car done?, does it feel "off" at any particular speed, or generally flat?
I had the spark plug leads replaced on my old 3.2 once, and it felt like I had gained about 50 Bhp [
] as they had obviously been breaking down gradually over a period of timePete

The car is well serviced so I would expect the plugs to be OK, however i think they are only replaced every 24k? I will be checking tonigh if this id due
It feels like its losing power at 3-6k range, just doesnt have the pick up unless you really give it a thrashing!
This means I don't quite get that kick in the back when overtaking or trying to do full power roll on etc.
and its done 125k
I'm booked in to TWG for them to look at it but they couldn't get it in before Aug 10!

I know 911 plugs are tricky to get out but 24k is too much even if that is what the service schedule says. I don't pretend to know better than Porsche engineers but just do the little bugger a favour and change the plugs every 10,000 miles, I do mine on my SC every 6,000. Has the air filter been changed recently? The point made about the plug leads is a good one too, also check the state of the rotors in the distrubutors and the dizzy caps and all their connections including the the coil.

No the official service schedule for spark plug changes on a 964 is 12K. Lots of places only do them every 24K. Also tappet / valve clearances are also 12K items that are also left till 24K by lots of places too.
Never had a decent explanation other than "but they are such a b*tch to do".

Could this slight loss in power be fuel or air temp related?
Wife used the car for day last week while low on fuel, enough to get there and back but she put a spot in anyway
She used a garge I dont but still used hi oct
Now the car seems to pull much better and the temp outside has dropped?
I've been using Tesco 98 ron could it be bad fuel?

Just collected the little beastie from the garage.
Full service, inc plugs changed, and check on power loss.
Cat is nearly on its way out and the sensor is stuck in it, they belive this is effecting the power as the senor is also jamed. They belive this is 90% of the power loss problem combined with the hot air temp in the last few weeks.
New sensor on order and do i want to replace cat or bypass?
From a cost point of view I'll do the bypass, anything else I should know?
