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 |
