Daewoo Korando - spark plugs replaced. Now it is misfiring any ideas

My Daewoo Korando recently had a mini service with spark plugs replaced. Now it is misfiring any ideas? The car starts fine but it is very difficult (slow) up hills. However, sometimes after it has been sitting for a while it drives ok.

If it ran better before you changed the plugs you can pretty much bet there lies your problem. To make sure all the plugs are on correctly slide the boot up the plug wire till you see the clip (this may not be possible on some wires), push it on the plug and then push the boot down over the plug. Check that all the wires are firmly pressed into the distributor, they sometimes get pulled out when being tugged on replacing plugs. If that's not it you may have gotten a bad plug or one could have been dropped and cracked the porcelain on the plug. Check the gap on each plug. But being sporadic and the plugs and wires recently messed with I'd guess one of the wire clips is touching but not snapped down on the plug.

Surging/loss of power up steep hills in Daewoo Lanos 2001


This sounds like you may correct in saying a misfire. this sounds like a bad coil that looses power under a load. Is check engine light on?
If the light is on or not go to an auto parts store like auto zone.At auto zone they will scan the computer free of charge and give you a print out of any codes. the computer will store code or codes when it detects a problem. A bad coil will make it store a code or should.
see if there are any misfire codes, this code will help pin point the bad coil. if there are codes write me back and give me the code. I think this car has coil over plug ignition system. this just means instead of sparkplug wires the coil sits right on the top of the plug.
Also replace spark plugs if it has been a while since they have been replaced. check air filter too. a matter of fact if you have over 70,000 miles on car tune it up. plugs,furl filter if it has one, air filter and pvc valve and clean throtle body.
Okay, just checked it out, this car if a 1.6 engine then does have a coil but not on spark plug, rather coil with sparkplug wires going to plugs. try replacing spark plug wires and plugs first and if problem remains then replace the coil. let me know the results. good day

Misfiring


A typical tune up includes spark plugs, air filter, fuel filter, spark plug wires, distributor cap and ignition rotor. You must determine which parts are needed before you start.
I would suggest to first check spark plugs and spark plug wires.
