had this problem really bad tonight when it started to really rain, it was running perfect all day before the rain started. basically its doing this

pulling off a junctions foot to accelorator floor speeds not picking up juddering, when driving its juddering speed is sticking at 50mph in a 70 zone revs stoping the same and then all of the sudden the speed and revs pick up for a few minutes.

i done an paper clip test and theres no faults coming up

i have changed and tested the following,
replaced spark plugs
replaced coil pack
replaced fuel filter

checked the resistance in the leads and they are all reading 5v's roughly nothing stupidly high or low
checked to see if theres any hydrocarbons in the coolant bottle on the emmisions tester at work and it was on 0

could it be this, even though the resistance in the leads are okay but due to damp weather and rain could it cause the leads not to work 100%

just check all wires towards th front of the bay arent open to the extremes as so to speak

as after dave rebuilt my engine, my dash went funny in the rain. but it was just some wiring in the front of the engine bay that had been pushed infront of the grill instead of where it was like 1 inch higher
