My car started to run not so great. I kept it limping along and when I tried to push it to cross the street the car shut down and will not restart but cranks very easy. Took it to a mechanic who said the timing belt isnt broken but when it cranks pressure comes out the intake. Also gives a message the the cam timing sensor (one in the valve cover) is bad. I tend to think it jumped several teeth. I havent done anything with it cause in south florida it is like a 110 degree sponge out there. The mechanic wanted to replace the whole motor. Just let go from my last job and I cant afford that. Any ideas? I feel running a compression test is a start. What else?
