Chirping noise when I accelerate
 

Hi guys,
You guys have solved alot of my 99 Disco II questions and problems. I have another issue now. I have a 1999 Disco II (127,500 miles). My check engine light came on about a week ago. I had the codes read. The faults were P0304, P0305, P0306, P0308 & P1300 (random misfiring). I know what the codes mean. So, I bought new Bosch plugs and wires. The check engine light is no longer on. But, I still have the chirping noise when I press the accelerator. Could it be an exhaust leak, bad pulley, tensioner belt or some other engine issue?

Go read my reply on your other site and do your homework.

When my front drive shaft u bolt was going bad it chirped.
