I can’t find a way to search the forums for topics or key words either. The Home page search doesn’t seem to do it. It only finds videos.
Thanks[quote=”astrudwick75″ post=35954]I have a 1999 Acura CL 3.0 that has the J30A1 engine in it. The car has 149,00 miles on it and is misfiring. The codes I am getting indicate a random misfire on all 6 cylinders. Things I have tried: change plugs, wires, and ignition control module. Gaps are correct and the distributor has a tiny bit of oil leakage but nothing major. I have been to 3 different places to have the car looked at. The first place (a Honda dealer) told me my #4 injector was clogged and needed to be replaced after looking at the car for 5 minutes (didn’t believe that), the second place told me that the distributor leak had fouled the ignition control module (why i replaced it with a junk yard one which did no good, neither my original nor the new one had any oil on them and no signs of corrosion), and lastly at another Honda dealer I was told that the car needed to have the valves adjusted because there was too much air as indicated by my MAP sensor. My question is, can Valves out of adjustment cause a misfire or is it something else. Valves aren’t clicking but I do not believe they have ever been adjusted. Another thing is that this problem started about a month ago and then went away for about 3 weeks and started up again over the weekend. Also the car runs smooth sometimes when I first start it up in the morning but once it gets warm it starts misfiring again.[/quote]
Hello,
Yes valves can cause misfires! I had the same problem with my Accord J30A1 engine and the valve adjustment solved my random misfire problem. I also had a rough idle. See my post #35261 on page 3 of this topic.[quote=”astrudwick75″ post=35954]I have a 1999 Acura CL 3.0 that has the J30A1 engine in it. The car has 149,00 miles on it and is misfiring.

I have an ’02 Accord V6 with 215k miles on it that had random misfire codes and a rough idle. I tried a few things but nothing helped. I used your videos and adjusted my valves. I found that my exhaust valves were very tight. I didn’t take any pictures, but my engine was very clean from regular oil changes. Now the car idles and runs like new again. Thank you for saving me a lot of hassle and money once again. Please keep up the great work!Frank
