Revs dropping

[Mathematics]

Hi all had to replace my battery today after TVs just dropped and died in traffic. Had the battery tested and it was curtains for the battery.

since then I have noticed that when coasting the revs drop done to around 500rpm and then rise quickly back to around 800rpm which is normal idle.

is this an issue or indicative of an impending issue?

thanks

Thanks doctle, but I won't get chance to get it in til at least the weekend. Is there anything I could try or look at in the meantime?

Check all vacuum hoses are tight and the air filter is clean. There's not much more you can do until it's scanned, is the temperature sitting at 90?

It may well be, it's only started doing it since battery issue

It needs a scan to eliminate the CTS

Coolant temperature sensor I think?

Happily to be corrected though!
