what will cause fuel smell stuck open purge valve
1. voltage spike not high enough on one failed spark plug
cylinder
2. flashing check engine light misfire
3. a catalytic converter turns hc into c02 and h20
4. during cylinder leakage test air es- leak at intake valve
capes at the throttle body
5. a car with this will not start bad crank sensor
6. in efi fuel pressure is controlled by engine vacuum
7. if egr valve goes out the fumes can go rough idle and stalling
back into the intake and cause
8. injector pulse width is the time an injector is open
9. the carbon canister is a part of the fuel recovery
10. white spark plug tip too hot
11. a leaking intake manifold can cause a lean condition because additional air makes it
into the combustion chamber
12. a fouled sparkplug would increase emissions
13. runs rough and backfires around throttle body
