1986 porsche 911 Surging: Low rev high rev. .

Car been mothball for quite a while, when I finally got her started idle was good. after arming her up for about 15 minutes I gave her a little throttle, she instantly started to surge. Any idea what could be causing this, seeking! In the middle of building a smoke machine to check for vacuum leaks, any points would be appreciated..

    The surging was caused by a bad reference sensor: This sensor reads the sensor pin on the flywheel and sends a signal to the deme to regulate spark and fuel. Plus.

Besides a leak on intake I will check the ECU just to make sure that thing is working as it was intended to, a sitting car usually have moisture build up and is not friendly with electronic components.

Porsche 911 targa at idle it would spit and drop off but not stall .it drives and revs fine


It could be something simple like bad spark plugs, clogged air filter, or bad gas. Start troubleshooting there first and see if the problem gets any better.

1984 porsche 944 2.5 na when the car is idling it will constantly rev up and down between 1 and 2k revs unless the idle control valve is adjusted inwards. Also when i press the throttle it does not rev...


cleaned out the fuel pressure regulator with carb cleaner, then dry lube spray into it, then my 944 turbo ran perfect. Also check coolant level. look for fuel diagram on internet if you cannot find the part.

I have not started my 911 in over 3 years. Oil has leaked out, battery is dead. What steps should I take to get this car up and running? How much would it cost if someone else did it for me?


first drain the gas out and put fresh in (hopefully the fuel hasent turned to varnish), it wont hurt to change the fuel filter, get a new battery, change the oil, check all the other fluids.

once you've done all that try to start it

Check your spark plugs, fuel filter and fuel pump. Basically car needs spark and fuel to remain going. Check all those and replace when necessary.
