    Hey boofoo, Well I just took it into a very highly rated shop here in town to have the timing belt replaced. He agreed that the mechanical timing was off by one tooth. When he looked at the belt and the tension he said both looked great and said that most likely the belt was installed off one...

    Thanks boofoo, that makes sense. Can you tell by these three photos if the mechanical timing is off? These were all taken with the engine cold. All the marks on my crankshaft pulley are white b/c I had to fill them with chalk to see them at all. It looks like from my manual the two TDC...

    Well I have more data, and a little improvement in the car behavior, but still missing at idle. In the time that this forum was down (I wasn't sure it was coming back up!), I posted on Civicforums and someone there recommended a valve adjustment, so I did that while waiting for my tach to...

    Thanks boofoo. I seem to have lost access to the forum for about a week there. Anyways, I am getting a tach soon, so I hope to work on this in a few days. It is an automatic transmission. I did get a timing gun a few days ago and warmed up the car for about 4-5 minutes, and revved it for...

    Gotcha. Well before I replaced the spark plugs and distributor rotor and added oil, the engine was sometimes running normally when I pressed the accelerator. More often than not it would hesitate for a second on the accelerator press and it also wouldn't accelerate as quickly as it should...

    Shoot. Hey, I don't hear the knocking, is it in pre-knocking stage before it develops a knock? Or am I just not hearing it (or maybe there are other symptoms in the video you're seeing that I'm not aware of)? I haven't had time to research next steps, do you have any suggestions for other...

    Here's a video, the squeaking isn't as easy to hear on this, but you can hear and see the engine trouble. vimeo.com/242678209 vimeo.com/242678120 I parked level and checked the oil again today. The reading was in the middle of the two marks, so I added a quart. I also added a quart yesterday...

    Hey boofoo, thanks for sticking with me! I installed the new spark plugs and distributor rotor yesterday evening, just before my last post at 7:09pm. I then started the car up and it proceeded to run smoothly for about 3ish minutes. I realize now maybe it was running more smoothly (shaking...

    Yes, I believe I see the charging system light every time I put the key in the ignition, but I'll double check tomorrow. I did install a new distributor rotor. The old one was actually in bad shape. It looks like the center piece on the circular rotor was completely black with carbon/melted...

    Yes, wide open throttle on all tests today. I think I saw a video where they called it a blocked throttle, maybe because they were using a block to keep the throttle open. I used a rope today to keep the throttle fully open rather than depressing the accelerator. I wanted to make sure that...

    Thanks for taking the time to read my post and help me out. I really appreciate it. I replaced all 4 spark plugs today with the same NGK V-Power spark plugs that were in it. I have never seen the charging system warning light on at any time. I did not replace the distributor rotor, but I...

    Hello from Santa Cruz, California! Hoping somebody can give me some advice, as I'm running out of ideas. I've had a reoccurring issue for the last 2 years or so where my Civic will misfire, mostly at idle. I replaced the spark plug wires 1.5 yrs ago and that seems to have solved the problem...
