It might well be the O2 sensor.

Only reason I'd ever be reluctant to seafoam is that I'd worry about gunking up my cats and killing my O2 with the smoke..

I'm sure Baltowolf knows--being in Cali like me--that those will be reasons enough not to do it here in Cali where the full functionality of those parts can be critical to whether you get to drive your car at all on the public roads.

I have a friend in L.A that will smog any car and get it to 'pass' without a problem. I already did seafoam and it didn't help, I seafoamed days ago lol.

With that being said, I would only do that in an utmost emergency, because I would rather not pay 200$ every 2 years for my car to pass smog, just buying a new cat would pay for itself in a single year.

Idk why but I thought I posted this hours ago but I guess it didn't stick? I have no idea what happened. Anyway, I finally did a compression test and here are my results.

Cylinder #4 = 180
Cylinder #3 = 180
Cylinder #2 = 160
Cylinder #1 = 165

I'm not sure if this warrants concern or if it's ok, but a 11.2% variation from highest to lowest is worrysome, as I have read that 15% is when the CEL will kick on for a mis-fire.

At a 9.4:1 compression ratio I think you should see about 200 on your test, ideally. I've seen people not complaining about 180+ much. Adjusting valve clearance, I read, by increasing it--perhaps to max spec.--can help with compression. Did you check clearance on #1?

All I used was a compression tool from O Riley and hooked it up to the spark plug holes. How do you adjust valve clearances and all that stuff?

Hi guys, I want to replace every single light on my dash with led's, anyone know what size? I keep reading a single 194 and four 74's but, I also read three 194's and four 74's??? Anyone know what the number is? I'm doing this for the 'cool' factor for when I get my car repainted purple.

I think it is this unless you want to get just generic LED's and DIY...

194 Only? That's kinda hard for me to believe that only 194's are needed...

Take it apart and double check. I bet the 74's are for dummy lights.
