Hey I will check that tomorow, i took the pipe off the brake servo and there was good vacuum when i put my thump on the end of the pipe, but didnt seem to make a difference in the running of it which must meen its something else maybe?

Hey is that the sensor on the intake manifold, there are 2 next to each other?by the thermostat and radiator hose?

well its not the brake servo, i tested it, im at a loss now could it be the coil or alternator? I heard the alternator can cause miss firing if its had it? What is the normal voltage it should be putting out? Also how do i check the coil?

New plugs still the missfire, brakes still heavier than before, how do i test though to see if the servo has gone?Could the missfiring cause the vacuum from engine to drop hence the heavier brakes? Also pumping the brakes makes the braking heavier when i pump them!

Just thought I'd run it to see if there was any difference before putting new sparks in and there wasn't but now today i heard popping and the power dissapears and the brakes have gone really heavy + the rich fuel exhaust smell any ideas?

Cheers mate gonna do the plugs tomorow, see what happens, if it doesnt cure it I'll repost cheers!:)

Haha not to worry you dudeness jk, yeh well plugs are coming out tomorow gonna try them, leads are all on fine, its just weird that short time of it working properlly, then running as was before(****e). I took some of the plugs out and put them back in that was the only other thing i did when i...

Hey dude, it was only today it ran good for a bit when i changed what i did, as i said didnt change the plugs. But then it started running **** again after shutting it off for a few mins. Ive had it for a week and its been doing it since I got it so just wondered if it could be spark plugs?

Hey I just got a Rangey with 108000 miles. I've been having a puzzling misfire which causing lumpy idle and lack of power thorugh the rev range, sounds more like a 5 cylinder car. I changed rotor arm, distributor cap and leads. Ran tonight and it ran incredible, all the power was back and...
