Occasionally when I start my car it starts up with a lower tickover than normal and won't rev cleanly. Looking at data logger it is almost off the scale lean (18.6) and although the PW is over 4 compared to around 3.0 normally it ticks over 4-500 rpm lower. Normally if I switch off and start again it runs fine.
Help this is driving me mad.
Full race Imp engine with GSXR600 TBs on TPS not MAF.
When it starts ok it runs fine and normally just switching everything off then on again resolves the issue.
Help-intermittent fault?
