    My truck is doing the same thing if you read in the owners manual it says what it means if it is flashing and what it means if it is solid. mine stays solid for a while and every once in a while it flashes the books says something about the emissions are misfiring

    I have an 04 and just had the same problem. Light was on solid for awhile but just started to blink the other night. Took it to dealer and #'s 5 and 8 injectors were clogged. It did start idling a little rough, so you may want to look into that. I'm trying to get a straight answer on where the fuel filter is on it. Unfortunately, I'm learning it might be in the tank!

You'll need to get the trouble codes read from the truck's computer memory. The Check Engine Light comes on when codes are stored. You can go to an auto parts store and ask if they read them for free, buy a code scanner, or take it to a shop. Without those codes we'd just be guessing at what's wrong ;-)

If you get the codes you can look them up here for more info or post back here - http://www.obd-codes.com/trouble_codes/

2000 silverado 4.3 V6. Replaced feul pump and niw it starts but it takes 3-4 cranks in the morn to start it and then it runs very rough untill it has ran for 1/2 to 1 hr. Also have replace fuel filter...


The rough running should have caused the check engine light to come on. It would be a good idea to goa ahead and scan the engine for trouble codes. The rough running could be a number of things. The codes would help us pinpoint the correct part ot replace, rather than start replacing parts until we get lucky and hit the right one. That could be very expensive.

In the mornings it runs very rough for about 15 minutes then its alright rest of the day. Then the same thing the next morning.


I'm taking for granted that you have a 5.4 liter engine, first is there any check engine light? sounds like it may have a bad cylinder head temperature sensor or possibly a fuel pressure issue.

Service engine light comes on and lose power


Well for one you already paid them $90.00 so make them fix it right. Second of all it could be many things. What are the codes? If your service engine soon light is on there are codes set. Does the car run fine when cold then as it warms up does it start to run rough and eventually die?

2002 1500 rough idle wont go over 35 mph service engine soon


Have you O2 sensors checked out. I have blowen out 2 on the same bank, sounds like the same problem. Check engine light will stay on solid, blink for a while, solid. Surefire way to check is run your finger in the tailpipe after it is cooled down. If it is very black with soot, then it probably is the O2 sensor.

2003 Silverado rough idle, idles good after "check engine" light


Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.
