Hi all,
Just recently,I have been experiencing erratic idling and revs racing on my 1992 RRC v8 efi ( pre-cat).
When I start up from cold or hot, the engine imediately races up to about 2000-2500 rpm for a few seconds, then comes back down to normal tickover. This has the added effect of switching it over to gas straight away !Then when driving along (with engine at normal running temp.), when I pull up at lights or junctions and have to wait a while, the tickover drops slightly then returns to normal.Sometimes if I rev it slightly upto say 1500rpm , it stays there for a second or two after I take my foot off the pedal.
I have also noted that it now takes a couple of cranks to start from cold now , whilst for the last 2 and1/2 years of ownership , it has always fired up virtually on the button ! I have replaced the sparkplugs with no improvement in start up time.When the engine is warm , it starts on the button.
Any help gratefully received.
