Symptoms as described above: At idle, the car sounds and behaves fine. No problem starting. However yesterday at highway cruise, momentary loss of power occured at irregular intervals, accompanied by occasional backfires.Power loss duration was from split second to up to 20 sec. About 2 weeks back, the Smog check mechanic stated that the hoses to the evaporation canister are cracking. He also adjusted the timing by several degrees, making what I thought to be an occasionally rough idle.
4 yrs ago, I replaced the failed original air mass meter.Could the problems described above be from the evaporation canister hoses being more severely cracked? What is the function of the evap canister during highway-speed cruising?
My first suspicions are for air mass meter, but the fact that cracked hoses exist on the evap canister make me want to understand that system better. Any help appreciated!
