i have a 97 type r and today it has started to tick over a bit high 1500 on tickover no engine light on all gauges are reading fine
any ideas before the weekend im gonna miss the mcrae gathering

 

I had a similar problem with my r the other week but mine was dropping down to very low revs on idle.
I took it to Zen and it turned out the maf sensor was on the way out so changed that reset ecu and its back to normal now.
