97 2.4 Petrol Running Rough when Damp

[Hewey]

Hi All,

My 1997 SWB 2.4 Petrol Terrano seems to run rough when its cold/wet, but only after driving approx 1 mile, then once fully warmed up after a while it then runs fine again.

It starts no problem and seems to run fine until I've done about a mile in it's as though it's only running on 3 and starts to miss.

Plugs are good, just wondered if anyone had come across a similar problem before I just start changing bit by bit and what the most likely cause is.

Cheers

Sounds like normal sort of petrol engine damp/water issues. Change cap, rotor arm and leads they're probably perishing and leaking to earth.

Its just the moisture earthing the sparks out - once stuff gets warm the moisture evaporates.

Cheers HB,

Thanks for your advise, wasn't sure if it was MAF related (which I presume it has??) I'm no mechanic as you can tell?

Will get them ordered, where do you go for your parts?.

Main Stealer!, Milners, Japarts, japanese4x4spares, other?

Stuff like that I get from my local place but I'm very lucky I have a massive independent auto factors near me. Milners would probably be next if they didn't hae it though.

A good tip on stopping damp problems is coat connections etc with electrical silicone grease. Works every time.
