Engine Performance problem
2002 Mazda MPV 6 cyl Front Wheel Drive Automatic 83000 miles
Hi, intermittent engine misfires started about 4 months ago, so I had the MPV tuned up. The tune up slightly corrected the problem but the problem is definitely still there. I found the exact same problem, some one else had, listed on your web site under "engine misfires". Here is a cut and paste:
Question: 2002 Mazda MPV mileage: 55,000. What is causing the intermittent engine miss I get driving at highway speeds? My mechanic cannot find the problem. I have replaced spark plugs and wires, CO� and temperature modules to no avail. During a 100-mile trip, it may not miss at all or it could miss sporadically several times. The misses may last 10 seconds or continue for several miles. The check engine light has never come on. It was put on a scanner and there were no trouble codes. Thank you for any help you may have.
Answer: It sounds like your van is ready for a simple tune up, replace spark plugs, plug wires and service throttle bore and IAC (idle air control) motor and passages."
The tune up I paid for was $600 that replaces the spark plugs, fuel filter, air filter, oil and filter, fluid flush.
Is there anything else that could be causing this problem?
have the same problem?
