can anybody tell me if the fuse boxes are a weak point on '89 xr4x4 as i am having a few problems, headlights won't come on unless you wiggle the relay, stereo switches itself on n off, but the main issue is that at between 900-2000 revs for a split second the car cuts out causing a rather irritating hiccup (being very polite aren't I) but this only happens when cruising at 30ish once the revs pass 2k all is good until you need to bring car back down to tickover, when this happens the revs drop down to around 4-500rpm for a few seconds before picking itself back up to around 900. Can anbody shine any light on any of these issues please . . . .before i do something that i might regret . . . . cheers Ged.
