Hi all,
I have 1999 4.0 sport - has run perfectly for years, however recently it has developed a misfire when first driving the car. No issue starting the car but once I get off the drive and take it up the road it pops and bangs and judders until I floor it and it all seems to clear and then drives perfectly for the rest of the journey.
If it's popping and spluttering and I pull over the revs seem to be very erratic, up and down. Like I say if I rev it up though it revs nice and smoothly.
Has anyone come across this before?
I have replaced plugs, leads, coil, rotar and distributor cap so far.
I'll add, no codes or engine lights are logged at all which makes diagnosis very difficult.
Thanks in advance
