Dont know really about running low on oil or overheated or anything, its not mine I am just working on it for a lady friend....I do not notice any smoke coming from the tailpipe except when one of the plugs goes closed... it does have 127,000 miles on it so it is getting up there...

i guess process of elimination that is cost effective could work - but timing belt may need to be done if it hasn't already. clean it, crank it, blow it out, crank it an blow again - install plugs an see what happens... O2 sensor costs less than timing belt...

#19 of 20 Miss fire on front 3 on a 2003 by slewisomaha

2003 v6 with 105,000 miles running rough at idle. figured it was a misfire & it was on 2, 4, 6 (the back 3) full diagnostic was done at the shop & replaced the wires & plugs. It's still running rough on 1, 3, 5 the hour after the plugs & wires are done. just spent $300 on that service. Any ideas on what would cause this jumping of misfire from side to side?

does that car have coil packs or distributor cap + rotor? my 1st guess would be fuel injector problem or cap+rotor issues... misfire due to plugs usually doesn't occur on so many bat once... did you have all plugs changed? what brand of plugs in the car?
