Owner, It sounds like the engine is trying to operate with too much fuel, this could be caused by a host of possible faults, including faulty fuel injector, faulty oxygen sensor, coolant sensor circuit open, possible evap system fault, Hint: never add more fuel after nozzle shuts off when filling tank.
There are some really good technicians in this business, but I don't know of any who are able to diagnose a vehicle effectively without test information, that being said, check for a vacuum leak, mis-routed spark plug wires, missing or incorrectly placed grounds, mis-routed vacuum hoses, loose or cracked intake duct, ignition system issues, or fuel injector connections & harness routing. Good Luck !
Lab Scope ignition & fuel pump relay control circuits, to determine which goes away first. does it have an aftermarket security system ?
Vehicle Owner: Sorry, we need more information to offer a possible solution ! any good Auto Technician would start with an interview of the customer, getting all the information about the failure, repair history, maintenance schedules,scan tool, check for communication & diagnostic trouble codes, test the battery voltage, check fluid levels and condition, check fuel pressure, & check the ignition systems operation, We make our diagnoses based on test results, not a guess.
Please describe the alarm sound, beeping horn ? steady horn ? Security light flashing ? siren ? More information - for me will help me - help you.
I you could provide me with the VIN #, I can give you an accurate Estimate, Thank You.
Yes, That is good advice.
Possibilities: fuse, ignition switch, wiring harness, faulty ground, power supply, consulting a professional technician is usually the least expensive, most cost effective solution to the problem.
Possibilities: Faulty ground, faulty transmission control module, wiring harness issue, connector issue, faulty throttle position sensor, Recommend consulting a professional certified technician / repair facility.
Possible failed engine mounts, driveline slack, ( faulty axles ), internal gear component wear, or: The transmission controller raises line pressure in response to a failure indication, ( slipping ), this is accomplished using an Electronic Pressure Control solenoid, which normally changes line pressures due to different engine loads, & gear ratios selected by the driver, including reverse. The EPC may stick in a high pressure position with debris contamination, which is only resolved with transaxle rebuilding or replacement. Recommend consulting a professional technician.
