main problem automobile is shuddering and hesitating if driving at any kind of speed. Most people I spoke with does concur the is sounds favor the MAF sensor and/or vacuum leak somewhere, however here are much more facts that uncovered out today. Ns think the separation, personal, instance at the auto part store was using the wrong form of scanner for the year of mine car. I took it and a mechanic to view why it would scan. Of course this was before I just found out i could check it myself. In any type of case. That seem come think either a negative ECU or the code for crank sensor is legit. According him the ECU is more expensive but an easy fix and also the crank sensor was much less expensive however harder to get to. However, just more investigation ns seem to have a coolant leak which got on come wires and also such and also perhaps out the exhaust. My concern to friend gentlemen currently is what is your opinion ~ above this assessment and also what exactly might in reality be damaged by this coolant and could this cause all the difficulties I defined previously. Will there it is in other problems forth coming through this and also what need to be the solution and also estimated cost for repairs. Don"t want to be took on this one and also finally what is the best and also the worst instance scenario here? thanks again gentlemen for her replies.
