You should have a code stored if this is a engine misfire. But most likley, providing nothing major is present, then I would suspect you need spark plugs and a coil may of failed because of it.

Fan is not working on 2001 Chevy Silverado 2500 truck radiator fan motor?


The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block.
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the low speed fan relay coil, closes the relay contacts, and supplies battery positive voltage from the low fan fuse through the cooling fan motor supply voltage circuit to the left cooling fan. The ground path for the left cooling fan is through the cooling fan s/p relay and the right cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the high speed fan relay and the cooling fan s/p relay through the high speed cooling fan relay control circuit. This energizes the cooling fan s/p relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the high speed fan relay coil is energized closing the relay contacts and provides battery positive voltage from the high fan fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
Your best bet would be to take your vehicle to a qualified repair shop !

My car 2008 Chevy Uplander warning light came on stating A/C shut off for engine protection. My question exactly as 1posted 2011. Gauge not Reading. Fan running continuously. Doesn't seem hot.


What gauge not reading , Temperature ? you posted back in 2011 ? You did feel you should take it to the repair shop ? You need to take this to a ASE certified repair facility ! This is a complex electronically controlled cooling system , Three relay's controlled by the ECM -engine control module turn the fans on in two different speeds ! There could be DTC'S diagnostic trouble codes stored in the ECM, HVAC module , BCM !
Circuit/System Description
The engine control module (ECM) commands the fans ON in high speed or low speed. In low speed, the fans are configured in series. In high speed, the fans are configured in parallel.
In low speed operation, the ECM applies ground to the coil side of the low speed fan relay, which is the Fan 1 Relay. Voltage is applied directly to the left cooling fan through the switch side of the low speed fan relay. The right fan is connected in series to the left fan through the de-energized Series/Parallel relay, which is Fan 2 Relay, so that both fans operate at low speed.
In high speed operation, the ECM applies a ground to the coil side of the low speed fan relay, the Series/Parallel relay, and the high speed fan relay, which is the Fan 3 Relay. Voltage is applied directly to the right cooling fan through the switch side of the high speed fan relay. The left cooling fan obtains voltage through the low speed fan relay and ground through the Series/Parallel relay.
When the ECM is commanding a fan relay ON, the voltage of the control circuit should be low, near 0 volts. When the ECM is commanding a fan relay OFF, the voltage of the control circuit should be high, near battery voltage.
One of the relays could be stuck on ! An for the gauge you have to have it removed an fixed , there is a stepper motor behind the gauge needle an they go bad ! Or replace the instrument cluster !

Why my driver fan is working onl Hi level only


I guess you mean inside the cars heater fan the switches contacts went bad if you mean the engine fan I don't know what kind of car this is but there are fans that have a low speed & a high speed and if the relay went for low speed you would only get high speed but because of the high weather temperatures and where you are could be the reason the engine is calling for high speed all the time I'm trying the best I can for the limited information you have given

Have the battery check. Low voltage does bad things to cars. also check the started while you're there; take them in to your local auto part store, checking is usually free.

Random misfiring on pistons on a 1996 chevy suburban


1st thing to check is the intake manifold for vacuum leaks, also check and make sure the EGR valve is not leaking when it is closed, to check the intake buy a can of carb spray and sray around the top of the engine, if a leak is present there will be a very noticeable change when the spray is near the vacuum leak. To check the EGR Valve start the engine cold, wait a minute or 2 then spray water on the EGR, if it steams up the water it is leaking exhaust into the engine, this will cause a rough run as well.
