2004 Chevy Trailblazer Variable Timing Solenoid Oil Coming Out
The variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the check engine light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern. Joined the variable valve timing game. They’re coming out of warranty and in-to your shop. Twisting pretty much describes what GM is doing with its camshafts today. Valve timing improvements used to be accomplished via camshaft lift. Such as the Chevy TrailBlazer.
Please read before Commenting. No, it's not the throttle body.Sorry, posted this in the wrong section of the forum.Problem I've had for a few years now and has been making me pull my hair out trying to fix it.When the car is idling and AC is on (and especially after the engine has warmed up), the car will start to run rough, and occasionally the rpm's will drop from it's normal idle at 600 down to somewhere around 200-400, and once in a while it will stall. Whenever it does stall out on me, it will always start right back up.I've never had a single f.@king code popup. The closest is every now and then the check engine light will flash on for a split second, but I can never get any codes from it.These are all of the repairs that have been made to my car in the last few years. Do you have the stalling/almost stalling issue only when the A/C compressor is engaged?Depending on the above.
2004 Chevy Trailblazer Variable Timing Solenoid Oil Coming Out Of Life
At idle I would do a power balance test. It is possible you may have an under-performing cylinder and when the A/C is on, it causes an issue.
The slight blink of the check engine light could be indicative of a misfire (but should throw a P030X code), so that may not be it.I would also check the fuel pressure as well as a cylinder compression check/leak down test of all the cylinders if I could still not make a determination.Good luck-Karl.
In this video we discuss (and rant) common problems with Chevrolet TrailBlazer and GMC Envoy vehicles. Love them or hate them they are here to stay and driving (or being towed) to a shop near you!
