Hi
I've posted about my car before, sorry about asking more again!
I have a '75 1.8l L-Jet that I drove from LA to TX a month ago. Since
then it has assumed the position of many 914's, resting too comfortably
in the garage!
I'd like to ask several questions in hopes of stirring it from its slumber!
History:
1. The car ran fine from LA most of the way home. Toward the end, it
wouldn't idle, and generally wasn't "right".
2. I have replaced virtually all of the vacuum lines on the car. Most are
plugged now.
3. I have pulled the injectors and had them cleaned and flow checked. All
OK within 1%, was 10%
4. Compression (cold) is a little low, but consistent, 90 psi on all cylinders.
5. #2 exhaust is not getting hot. I have changed the plug and the plug wire.
No change. Plug is wet with fuel.
6. All the rest of the cylinders look a little rich, black. No fouling. Air leaks
indicate lean, right?
7. The car will not idle. It starts, rev's, and then dies. I can save it with the
throttle. It "seems" like it wants to go to a high idle cold.
8. Fuel pump runs continuously. Fuel pressure is over 30 psi all the time and
does not seem to drop as the engine "dies".
I am sorry if the description is out of order. Okay, the questions:
Questions:
1. Do you think the car should idle, however badly, with one dead cylinder?
2. What is the matter with cylinder #2? I changed the plug and the wire. It is
getting fuel. Oh yeah, dwell and timing have been verified. Dizzy cap is new.
3. How far open would you expect the idle screw on the throttle body to be? One
turn, two turns, more?
4. The mixture control on the air flow sensor is totally closed. How far open
would you expect it to be?
5. There are small backfires at the air flow sensor. I know this is bad.
What is the cause of these? Vacuum leaks? Why the backfires?
I am SO tired of this crap!!
Thanks,
Jeff
