My ckeck engine light came on, so I took it to get diagnoised and I was told to check my gas cap. So I bought a new one reset the light after 130 miles the light came back on. I brought it to a mechanic he says he can not find a leak played with some hoses and reset the light drove it the light came back on. I went to a differant mechanic and he said he was getting a 440 reading and the hoses going to my evap where lose, so he re-attached them and put new clamps on. He then reset the light and last night it came back on. How can I find and fix my emmisions problem if the three mechanics I took it to can't?
How many mechanics does it take to find fix an emmisions leak? on 2001 Pontiac Grand Am

Evaporative emission tests are something a lot of people struggle with they are often hard to locate. Some systems allow you to close solenoids with a scan tool that has bi-direction controls and can talk to the computer in your car and enable you to look for leaks.Many automotive repair shops have a machine that generates an inert non flammable low pressure smoke that looks similar to cigar smoke. The intake manifold is sealed off, and smoke is put into the engines intake manifold.
