Hello there!

It's been almost three years now since my Check Engine Light came on for the first time, because of the dreaded front/intake gaskets... YES...1997 4.2 V6...
I replaced them on time, my engine didn't suffer that much...Thanks AJRagno!!

I got a code two days ago, P0340, some about Camshaft Sensor Malfunction...is this an expensive repair or can I replace the sensor myself? Will it cause any damage if not repaired within 2-3 days?

Thanks people!
