could someone please shed some light on this. what happened was i did a ecu check and found the following codes:
32 lambda sensor
24 idle solenoid
11 crank sensor
13 cam sensor

reset ecu all codes went apart from lambda.
took it out cleaned with wd40 put it back in, then another reset and everything was fine no more codes.
now, 1 month later i thought i would check and see if any codes are on and yes all of them were back. so i reset ecu and they all went off. what i would like to know is are they all shafted, or on their way out? plus are they a problem as the car seems to run fine. car is a 95 mcrea edition.

you could have a dodgy engine wiring loom connector that is just on the verge of breaking down so miseed a few triggers. Is your battery in good condition? it doesnt struggle to turn over on a very cold day? If your lambda sensor needed a clean before clearing the code i would suspect that as genuinely on its way out.

thanks for reply, mentioning battery. if left for 2 days i wouldnt say it struggles but you do notice it has drained slightly. would this cause some probs u think?
