Get the codes checked.This will tell you what cylinder is causing the problem.If the wires and plugs didn`t help then you probably have a bad coil.Hope this helps.Good luck.

A couple of things come to mind. Double check the wiring at the fan clutch, check the whole harness, there is a known problem wth chaffing there. Is it a Dorman brand fan clutch? These have been known to be bad out of the box. The other thing that could be wrong is the actual speed sensor on the new fan clutch. Hope some of this helps.

Check engine light is on and the car runs rough at idle only. There is also a burning smell when I exit the car coming from under the hood. What could be the issues?

have a parts store pull code, to see what sensors r at fault, tps throttle position sensor may need adjust, oxygen sensor needs replaced, may have two ? both need replaced. gas cap might b faulty ? in any event, the trouble code must b cleared out from computer, after repaired is made. if engine light comes back on, reclear it. sometimes intermittant sensor problems occur, engine light comes back on. well, the gas we buy with ethanol is killing our engines, put some fuel stabilizer in @ next fuel up. but try some fuel injector cleaner first, winter gums up injectors, soooo ! fuel filter replacement is always in need, people don\'t get it, replace all filters, air, fuel, oil, get it ? maintenance is a necessary evil. u change yur clothes ever day, right ? well, same thing., good luck, ken

Rough idle check engine light

Could be any number of things. You may need to have a shop hook that scanner up again and look at the sensor readings. Also look at the fuel pressure and the pressure regulator.
As the engine warms up the fuel mixture should change, and that would be reflected in the sensor readings. The sensor data has to get out of normal range before a code is set and the warning light turns on.

I have a 2004 6cyl. trailblazer EXT. My check engine light has been coming on then going off for quite some time. Had catalytic converter replaced 2 years ago, put on new gas cap a year ago, and...

More than likely, you have a failed fan clutch. That is a frequent problem on the 4.3 I6 engine. It will cause a roaring noise and "vibration" and allow the engine to overheat at low road speeds. As far as your check engine light and other driveablity problems, it may or may not be associated. Have someone with a code reader check it. The TrailBlazers were infamous for electrical gremlins.

My fan clutch is trying to go dead and it made my service engine light come on and now my reduced engine light came on what should i do

First you need to determine what the fault codes are that are setting the check engine light, if it is pointing to the fan clutch, have it replaced. But I don't think a bad fan clutch will set the reduced engine power light, there may some other things going on, the codes should help.

1 have 03 envoy,6cyl,have replaced viscouis fan,fan still runs a lot, dealer has checked twice all ok

Do you have the check engine light on? If a fault code of P1481 or P1484 is coming up with a scanner, the fan clutch is bad.

Check engine light on....cooling fan over speeds. I replaced the fan clutch and still does the samething...a lot of air noise...specially when starting out / accelerating

Check engine light is part of the solution as the code stored may indicate the malfunctioning sensor.The fan overspeed is a computer generated safety backup for electric fan clutch engagement so the engine don't overheat when the coolant temp sensor malfunctions.
