1995 Grand Cherokee Engine Problem
Got a 95 grand cherokee. engine runs great if i got the gas down but wont idle at all. check engine light is on. took it to a shop and they said after scanning that the only problem was the batter wasn't holding a good enough charge. so bought a battery. problem didn't go away. alternator is good, plugs and wires are good. where should i look next? other symptoms are horrible fuel economy, soot coming out the exhaust, wont downshift correctly and sometimes will stumble when getting up to speed. all the electronics checked out....
