Our 94 Jeep Grand Cherokee Ltd has always started on the 1st try, but for the past 3 weeks the first start of the day takes us about 12 tries, and if it is damp outside even longer. My hubby has since given it an oil & filter change, replaced the spark plugs, and added some fuel injector, but nothing has made a difference. After the initial start, it is fine all day. Has anyone experienced this before? If so, how did you remedy it? We really cannot afford to take it to a mechanic if we do not have to, so any help is appreciated...thanks
