Help ?! Went in for a minor steering repair and they discovered a fuel leak .. had 3 fuel injectors replaced, now there is a recurring sporadic hesitation - feels like a hiccup ? Mostly when accellerating and more pronounced when cold but it happens anytime, up hill & down . The mechanic ( a good honest fellow ) had some trouble getting the compression right after the injector repairs but can't figure where this final problem is coming from..... can anyone point me in the right direction ?? Thanks in advance
