Hey R3V,
The car decided to misbehave a few nights ago. I was on my way to a restaraunt to meet some friends from work. It started feeling weak, and hesitating when I would give it fuel. Before long, the problem was so bad that I could give it just enough gas to continue down the road at slight deceleration. If I gave it more, it would choke and want to die.
I got it to the restaraunt (was nearly there) and shut it off. After dinner about an hour later, I went outside and started the car. It started lazily, and the idle quality steadily worsened. At first I could rev it almots freely, with some heistation. Soon it began to hesitate on revving, and then rev slower. Soon, it was idling very rough and I could no longer rev the engine - it would only idle poorly.
I knew I had a bad vacuum hose going to my FPR. While it was still idling, I pulled the vac hose off of the FPR to see if it made a difference. The car almost died until I replaced the hose (obviously I introduced a huge vac leak) .I brought back some vac line and replaced the connection. I managed to get the car started, but the idle quality was barely (if any) better than before. It eventually died and I could not restart it. I recently replaced my in-tank transfer pump with a TRE340. To be sure I had fuel pressure I pulled a line off post-pump and shot fuel everywhere :mrgreen:
I hooked it up with a strap and towed it three miles home. About a block from my apartment I was able to fire it up just fine. I idled it for two minutes or so, and could again rev it freely. I ran a couple laps around the complex, and again the ability to rev got worse. I let it idle, and it again degraded like before. Basically the same story.
I replaced the plugs with no difference. When I fire it up now it catches initially, and almost immediately drops down to a nasty idle and dies. Plugs do smell somewhat of fuel, so I'm not sure if its starving.
I checked spark before replacing the plugs, and it seemed somewhat weak. Pulled distributor rotor and cap apart tonight and they look pretty good with light carbon scoring on the cap contacts. The rotor looks good except that the plastic strip running to the radial contact blade has four tiny points in it... unsure if this is normal - should I replace these components?
Remember, the car fires initially so I doubt if this is totally spark related.
What should I test next? E30tech has been sleeping on this one...
Thanks,
Jay
