Hello,
I have a problem on my newly rebuilt 1.8L engine, with L-Jet. Yesterday as I was driving home the car simply quit about 5 blocks away from home. Until this point it was running very well. I had to have it towed home and now I started trying to diagnose it. So far I've checked that the fuel pump operates when opening the flap in the AFM, so I suspect I got fuel pressure right. The starter spins the engine well. I have strong spark on the main distributor cap wire (coming from the coil), and putting a brand new spark plug into one of the spark plug wires I have spark at that too. (Originally I was too lazy to pull an actual plug from the engine.) But this morning I tried pulling a spark plug from the engine, and it is completely black and covered in carbon. Not wet, just covered in a thick layer of solid black material. I can't check right now whether the spark plug from the engine is fouled badly enough to not give a spark at all, or if it still is OK. (I need to wait for my son to come back in the afternoon to help me, this is a 2-person job.) But assuming the spark plugs are the problem, can somebody offer a guess as to what could have caused the engine to foul the spark plugs so badly and so quickly as to stop the engine while driving? Before that there was no indication something was wrong. Other slightly strange things. a) I've noticed the car burns a lot of gas. I barely get 20 mpg in mixed city/highway driving. b) I have about 600 miles since the rebuild, engine ran well all along. c) The only other issue with the car is that I can not get the idle right: it seems to idle at 1800 rpm most of the time, but if the engine is well warmed up (after about 1/2 hour of driving) or if I hold off the clutch as I come to a stop until the rpm's come down to 900, it'll idle at 900. I've tried two different throttle bodies, thinking it may be the throttle that sticks, but it behaves the same way with both. I started to suspect that the distributor is sticky and does not retard the idle sometimes. Any suggestions, highly appreciated. Thanks, Andrei. |

mic and HAM, have read this whole thread? read pages 1-3 before you accuse med of douchebaggery, you douche bags. pg1 post 4 from me, rings. followed by others suggesting the same including HAM. the op does not adress the rings and i am the douche bag? re read then respond intelligently or i would suggest you suffer from affliction as the the op. Wow. Project much? You started with the snark, then went further and implied the OP is a troll. I snarked back and asked if you had a bad day yesterday, but don't think what I posted insulted you in any way. Now you are straight out calling names and insulting people. All I did was quote you as saying that the OP didn't mention his plugs were not firing until page three of the thread. I pointed out that the thread is tilted: "Badly Fouled Spark Plugs," and that the OP posted pics of fouled, poorly firing plugs on the second page. With that title, I would expect to see non-firing spark plugs as part of the OP's problem. and yes, I did see post four on page one. You were seriously trying to help. I think that you have convinced yourself the OP is a troll because he didn't listen to your advice about the rings. While others are still trying to help with the original question posted, you are sniping from the side and being rude. There is a chance you are right and the OP is a troll; I still give the benefit of doubt to him. Others here seem to agree that he is serious, they want to help him solve his issues. If you go back and read the thread, please notice that I was not the first person to respond to the unhelpful comments you were adding to the thread. I was only more direct and open in my post than the comments made before I posted. If that makes me a douche, cool. After all, I am apparently the unwilling ambassador of the Masengillian Contingency. You should be careful you aren't becoming one of us though...from what I have seen here, you could be one of our leading citizens... I actually feel kind of sorry for you. It bothers you so much that the OP might be a troll that you can't let it go and ignore the thread. It bothers you more that others are taking the OP seriously, so you question why and then you insult other forum members because they are trying to help the OP. It must also bother you that we don't see what is so obvious to anyone with half a brain. -- Whit |
