The car is running great and I just got a brand new starter and a brand new battery so I think its just another sensor but I’d like to know how many my car typically has before I rush it to the mechanic all worried about some big expensive engine problem.
oxygen sensor, throttle position senr, mass air flow snsr, manifold absolute sensr, intake air temp senr, coolant temp snsr, ect., ect.
Hundreds. Don’t try to change them hoping for a fix. Just take it in and find out what it is.
