Re: Knocking on front end
when you give the car to much gas and your rpms are low does the pinging noise occur? It could possibly by that your luggin your engine and driving with your rpms to low or your losing compression in your cylinders. Sounds like what happen to me!! Possibly your timing belt might be off too. Don't waste your money on a $120 diagnostic, ask someone you can trust about what they think the problem is.
