I Have a couple of questions. First question does engine surge when idleing cold? 2. Does engine start quickly without a lot of cranking, Cold or warm? 3. Do you have funny smell at highway speed, or after you stop? With out this info and your imput, I would only be guessing. I am retired mechanic of 25 years. and would like to help if u need me.

SOURCE: 99 chevy silverado running rough and stalling.

the problem you are discribing would lead me to belive your fuel filter is clogged which is a simple fix 3 dollar part at any part store or on the worse hand your fuel pump itself could be weak you can open the gas tank cover and have another person turn the truck key to the on position without going far enough to start you will hear a faint whining noise if it is going bad or a louder noise if it is fine Good Luck

2006 Chevy Trailblazer started to run rough in idle but only after it warms up. My mechanic got P0017 code on his scan tool and told me I needed to replace the Crankshaf and Camshaft sensors. Both sensors...


Bad coolant temp sensor or EGR valve stuck. You can remove and test temp sensor (the one for the ECM--has only one wire) using cold and then hot water and read resistance with ohm meter.

2001 chevy suburban,idles rough,check engine light flashes ,after truck warm up light go off and stop idling rough


Get a computer scan for trouble codes to see if that points you towards the problem. Possibly an engine sensor is not working right till it is warmed up. You might also check the idle air control for proper operation when cold.

5.3 liter Chevy engine #1 Cylinder not firing at idle


My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

(in my opinion)

Why is my 1994 Chevy S10 Blazer lugging? motor shakes and lugs.


Could be vacuum leak or bad ignition wire(s).

I had a similar problem on my "93 Ford probe. The engine idled pretty rough with shakes, Turned out to be a head gasket leaking engine coolant into the cylinder during low rpm's. At fast rpm's it was fine becuase the internal cylinder pressure was greater than the hot coolant pressure & would prevent the coolant from leaking in.

A friend has the same problem with his "94 Blazer 4.3 L, throttle body injection, manual tranny. He hasn't fixed it yet, It started a few weeks ago & is getting worse. His gets a fast idle with hiccups which causes the engine shake. He already checked the EGR valve. He also has a severe exhaust problem, Not oilly but very gray & terrible smelly, but only when the fast idle problem happens. THis fast idle hiccup problem starts when the engine is warmed up.
