    Default Vectra losing power & overheating

    Hi,

    Hope someone might be able to point me in the right direction I'm pretty much at my wits end with this! Have had the fault code PO100 popping up for a while but seems to be ok after the code is cleared. However, yesterday my vectra started losing power dramatically in 4th and 5th and overheating. I ran a code check with my reader and after 4 attempts this code came up again. Having read a few threads I changed my Air Flow Meter but this seems to have made the problem worse! Any help or advice anyone could give me would be an absolute lifesaver. (1.8 vectra 03)

    Thanks

    I had a 1.8 and I think they suffer from faulty thermostats a lot. Yours may be sticking in the closed postition. Would also check your O2 sensors. If the MAF was faulty it could cause the engine to over fuel which in turn burns out the O2 sensors
