Engine Issue,,,,,no it wasn't
New guy to the forum and have an engine issue I'm trying to zero in on. Have 1999 Disco I with 127,000 miles. No major issues to date, thank goodness. However, recently the engine has developed a stumble at road speed, starts around 1500-1700 rpms. It idles okay with no apparent misses and revving the engine not under load results in a smooth rev up. I have replaced the spark plugs recently and we pulled them all for a look and nothing jumps out at you...appear normal.
I put a can of BG44K and it seemed to diminish the roughness sometimes, but I'm beginning to think it was my wishful thinking. I thought I'd wait until I had run a tank of fuel through the engine before doing it again. The mechanic who sells the stuff says not to over use. Also thought I'd use it with half a tank of fuel versus the nearly full tank of fuel I did the first time. Additives I'm never really sure about, but some people seem to sing BG's praises.
Anyway, I have been reading with great interest some of the comments from "joey, and beemer and others" about injectors and am beginning to think I've got at least one that is not working properly. I'm thinking its okay for idle and lower rpms, but under load it just isn't doing its job. Would appreciate insight. For injector servicing I found this site and wonder what you guys think.
