long time no post, been lurkin a bit, ... anyway, love my 914 still, but a new problem is buggin me. it seems after about 20 freeway miles in fall/winter here in so cal, my car has problem idleing. say, if im going about 60-70mph on the freeway, for 20 or more minutes, and i exit, by the time im at the end of the exit, im in neutral, car supposed to be idling at about 1k rpm, but, it just dies. im temporary "fixing" or "dealing" with this by blipping the gas while braking with the left foot.

car idles fine when its cold, any hints?

thanks

Carbs or FI?

FI.. (dont even suggest going carb. )

check your mps and see if it holds a vacuum.

Mine did not, same symptoms.

do you have a decel valve?

"Idles fine cold"? Idle should remain high (1500 RPM or so) for 3-5 minutes before settling down to 1K. If it doesn't, you need to test and repair/replace the AAR. Points can cause this problem, as can a worn out breaker plate, the thing the points mount on. A rich mixture, and even a lean one, can cause this. As was already said, check the MPS to see if it holds vacuum. The Cap'n

how do i check if the mps is holding vacuum?

where is the decel valve? i dont know where it is.

If it idles fine cold, but not when it's warm then the FIRST thing to check is your valve adjustment. Odds are pretty good that your valves are too tight. Almost everything else that it could be will cost you money, but this is free (if you do your own). Besides, a lot of the other things that it could be depend upon proper valve adjustment or they won't be right either. Start with the basics, then look for more complicated things if it doesn't help.

Good advice, Ernie

Good advice, Ernie

will definately do the valves. thanks for that reminder.

how do i check the mps's vacuumness?

pull 15psi on the mps port from a vac pump thing from FLAPS.

if it holds for 5-10 minutes with minimal/no bleed-down then you're set.

I have the exact same issue - will check the valves, among other things!

and check your timing
