Hi there, I hope someone can help me with a problem. I dont know if this has anything to do with my problem but it happened right after I changed my oil. I change my oil in my 2003 mazda mpv van and i began to hesitate while im driving. Its like the engine hesitates 2 or 3 times. Sometimes even on acceleration it hesitates. Imagine it like your engine is bumping forward 2 or 3 times then is fine. I cant describe it. I put synthetic oil in it and changed the filter, but doubt that has anyting to do with it. Its almost like when you car is idling funny but when driving. It only does its intermittenly. Any help would be appreciated.

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Record whether the engine light appears and have the hesitation diagnosed before replacing parts. Give the technician the timing of the oil change and the reply's suggestions to assess the PCV hose and ignition coils.

Guidance references and applicability

Next steps are editorial guidance for obtaining diagnosis or clarifying the reported findings; they are not a verified repair procedure or an independently confirmed component diagnosis.

Try some fuel injector/fuel system cleaner. It's available at any auto supply store. Wal-Mart also carries it. You may have some moisture in your fuel.

Has the engine light come on at all? This souonds like it may be either a problem with the PCV hose (on the back of the intake...you won't be able to see it) or possible a faulty ignition coil.

Discussion summary

2003 mazda mpv problems when driving. Any help please

A 2003 Mazda MPV intermittently hesitated while driving and accelerating after an oil and filter change. The owner was uncertain whether the service was related.

Reported outcome: No test results or successful repair were reported.

The discussion did not establish that synthetic oil, moisture in the fuel, a PCV hose or an ignition coil caused the hesitation. The apparent timing after the oil change does not prove a connection.
