Tvrs3c misfire cylinder 4
Discussion
Hi I have recently bought a Tvrs3c about a month
ago, bought with rough running at around 2000rpm,I have since spent much time and expense with the parts cannon I bought at a reduced price to allow for expenditure.
Here goes so misfire continues at around 2000rpm,up until now I ve fitted leads distributor cap and rotor plugs coil ignition amp and throttle position sensor.
Today continued diagnostics following road test still the same.I pulled all plugs to find all in good health except number 4 no colouring just like out of box,pulled lead tried for spark no spark however if additional leads pulled from cap spark will appear,so tried another new cap and new leads still the same Dismantled distributor to check pick up and pulse wheel all look good including measuring pulse wheel contacts with caliper.At wits end only conclusion I can come up with is possible fault with ecu.
Ps I have also tried another known hood coil.
Any help will be greatfully received.
