    Hi I have a 2004 honda 2.0 VTEC ex
    i have had it scanned with error codes for the map sensor and the front cam position sensor
    i have replaced them and it has run better but today while driving home the car started to judder when accelerating and when I was sat at idle it stalled a couple of times

    i don't know where else I should be looking !!!

    Hi and welcome to AOC sorry to hear the issues with the car .

    What happens if you revert back to the old sensors and do a idle learn?

    idle learn is the process where the ECU recalibrates the engine idling so it stable and memorized into the ECU for reference.

    Search for it you will find it on the site.

    Woudl this account for the occasional juddering? and sometimes stopping me from going past 3000 RPM?

    if you can't get above 3000 RPM then you have a jammed VTC actuator which is due to poor oil changes.

    The best is get your car to a Honda trained technicians they can pick up issues looking at the car, if you were closer I would have had a look.

    I don't want to sound as a snob, there is a limit in how much you can read and learn and how much you can actually do without looking at the car.

    You need to seek help for a local Honda specialist and look under the bonnet, I don't want to give you hope on a miracle cure when this situation is far from easy.

    By all means come back and report back with your finding as it gives another insight. The answer to your question yes the VTC actuator can cause the above s symptoms but you have to check other parameters to rule that out .

    You have to give more detailed information to the current state of things with your car, than what you have given if you want to continue down this path of diagnosing the fault.

    MIL is the another term for Engine management light.

    Matt, the diagnoses and advise given by CJ (IchibanAccord) is spot on. Have a local Honda specialist look at it and report back to us.

    You need to remove the actuator and see if the wire gauges have dirt trapped in it. a DTC scan will reveal if it is or not, provided you have a OBD scanner.
