    MAP Sensor - Clean/Replace!

    Just wanted to throw this out there for anyone having idling or fuel economy issues. I've been slow replacing the major sensors on my 03 KJ. I always had a rough idle since I bought it 2 years ago, and it's slowly gotten worse. I finally came to the MAP sensor which many people said doesn't go...

    Negative battery cables?

    I am planning on adding a upgraded sound system. Nothing ridiculous. Maybe even some lights. I've heard AGMs are better at delivering more consistent voltage across the entire car. Especially under heavy loads? I guess its overkill now, but I'm looking at a Bosch AGM and Duracell AGM both are...

    Negative battery cables?

    Update: Solved the low alternator output! I had a chance to poke around today. I checked all the connections on the charging system and noticed the Alt terminal had some sort of build up on it. Took it off and scraped it down to bare metal. Looked like some adhesive from the heat shrink had...

    Negative battery cables?

    Thanks for the response. I used a volt meter to test for resistance around the engine while it was running. I found a 0.14 voltage drop between the engine and chassis. I think its causing my elusive electrical problems (13.1V charging, random misfires, low idle and dimming lights). I've...

    Negative battery cables?

    Hello all! First time posting on here.. I discovered a bad ground connection between the engine and chassis. Also the negative cables coming off the battery terminal are very coroded. I figured I would replace the negative to chassis, negative to engine block, and engine to chassis cables...
