to really step on the gas to gain. It reaches about 4000 rpm before it finally kicks in.

Lately my check engine light has been coming on. I have noticed a loss in power in my engine and it runs "rougher" than normal. Could it be cylinder circuit, and how can I check, diagnose, and repair it? I cannot find any mention of it in the manual.

What's a cylinder circuit? What do you get as an error code when you had the codes read?

Oh.... now some more of the secret emerges...... why didn't we see fit to mention the CEL earlier? Sorry guy.... I ain't gonna "cat and mouse" this thing. If you're not going to be forthright and honest with the problem, I will not waste time on it.

How abut we start from scratch detailing the problem and ALL the symptoms.... feeding info bit by bit makes the bill bigger, not smaller.

It's the OS Sensor on the bank 1 which is before the catalytic converter. My buddy will replace this for me as well as the fuel filter.

We're replacing the spark plugs too.

I'm saving tons of $ from Labor and parts. Good to have friends.
