Got a question guys. My engine has been idling pretty rough lately so I decided to check to see if one of my spark plugs was out. I check them, they're all fine. So I decided to check if my spark plug wires were bad, so as the car was running I pulled the wires 1 by 1. So I pull the 1st & nothing happens, exactly the same idle. I pull 2, 3, & 4, & each time the engine starts to idle more rough. This got me thinking that the 1st wire was bad. So I pull it out again while running & its still clicking (firing). So...:

1) Its not the wire or spark plug right?

2) Could it be that my damn cylinder went out on me?

Thanks in advance.

Try checking that cylinders compression. If all is well, replace the wire and check inside your dist.cap for wear. Good luck. Hope its just the wire. :wink:

i have a '91 240 that was idleing rough bout a week ago. i put some seafoam in the gas tank and it fixed it in just a couple miles. it's less than $10 at almost any car store. just remember to read how much to put in before u do.

sea foam wont fix this. if one cylinder isnt firing, its something that needs replacing or fixing. check compression, check fuel injector.

Whats up guys. Well I didnt wanna pay someone to tell me that I had no compression in my 1st cylinder so I researched a little and I ended up trying the Restore "Engine Restorer". It worked. I put it in at the Pep Boys when I bought it and drove to school, 50 miles away. Before I got to school I noticed a difference.

So today when I had a chance I checked under the hood. The 1st cylinder is back on. I let the car run, pulled the first wire, and immedietly noticed a rougher idle. Checked the other ones too and when I pulled those the car began to idle even more rough then before I applied the Restore. So Im pretty sure I have better compression in all the other cylinders too.

Thanks for the help though guys.
