thankyou for the fast reponses

how do i go about checking for air leaks in the fuel system?

also i tried doing a compression test shortly after getting the car. (5 years ago) followed all the directions got EXTREEMLY low reading. Threw it on my fathers 300cd (rebuilt engne 30k miles) got same results. returned that tester for a new one (different brand even!) still got wierd results. shrugged and kept driving the car fine for the last 4-5 years.

i guess i will have to take it to a shop to do a compression test since i cant figure out how to do it right.
