i want to know what can cause me to drive lean?? like the car have hesitation to accelarate. i want to know if a exhaust leak can cause that? leak from the header or cat?
or something else? i know it could be like thousands of causes but through the exhaust system what can cause the car to drive lean??
please all comments appriciate
i see what could be my problem but i dont know what i can do to fix it.
Engine hesitates accelerating
Dirty spark plugs i just changed it couples months ago
Problem with fuel injection system
Clogged fuel filter i change the entire fuel pump and filter
Engine control system fault
Intake mantifold air leak i check it and i dont see no air leak
so my possible two problems can be:
Problem with fuel injection system
Engine control system fault
what can i do to fix it?
thanks for your help
does the o2 sensor have to do something with that???
well im not too good at finding fuel related problems without a fuel pressure gauge and its really hard to hook one up on a sunfire because theres no service port so you gotta remove fuel lines
and yea a bad o2 sensor can cause rich and lean conditions do you have a scan tool or voltmeter? if ya do check the voltage readings on both o2 sensors and record em
oh ok i will check it tomorrow.
if there is a specific volt that the o2 sensors must be????
anything below 300 is too lean anything above 6-700 is too rich anything in between should be ok
sorry i mean in milivolts .300 .6-.700
