The drums should be inspected to see if they are actually round. Another possibility is a high spot on one of the brake shoes. The mechanic who adjusts the valves (ref: your earlier question) can pinpoint the issue for you...
I wouldn’t condemn the head gaskets just yet. Intake manifold gaskets are a common failure item on your Chevy's engine. When they fail, they can leak externally, or internally, or both. When they leak internally, coolant gets into the oil....
Hello. If this only occurs when the engine is cold then you may have a sensor reading incorrectly or you may have a vacuum leak. Most of the time if the Check Engine Light is on I start by scanning...
Have the power and control circuits for the injectors been tested? If the injectors do have power, but no ground control from the computer to turn them on there may be a fault in the circuit or the electronic control...
Hi there. Based on what you've described, it appears you have multiple ignition and fuel system component issues causing these symptoms on your Chevrolet S-10. The rich idle situation (causing the black plugs) can be caused by damaged O2 sensors,...
Hello. There are a couple possibilities including the fuel issue you have mentioned. If you spray additional starting fluid in the intake and it runs longer, then that's a clue that fuel starvation is the problem. See if you can...
Check to see if the Theft Light is on or blinking while you are trying to start the vehicle. Try another key to see if the problem continues. If it does, then have the vehicle checked for fuel pressure and...
You may have a clogged radiator cap so coolant can go into overflow tank and back into radiator. Check cooling fan clutch to see if it is locking up as it should.
Misfiring can be ignition or fuel related, not to mention the mechanical (engine condition) causes. If the air fuel ratio is off due to lean operation for example (vacuum leak, fuel pump failing, etc.) the engine may misfire. To distinguish...
The shaking is likely a result of the motor not firing completely and starving for fuel. It sounds like you may have a fuel supply problem in getting the proper amount of fuel to the fuel injectors. As you know,...
Hi Mari. Thanks for sending your question to us today. In most cases, a lack of acceleration like you're describing is due to the transmission slipping. Sometimes this is due to dirty transmission fluid while in other cases, it's a...
The ABS light and brake lights indicate that there are faults stored in the Electronic Brake Control Module or EBCM. These faults need to be read out to determine the issues in the ABS system. Now it could be something...
Installing a radio should not cause any issues unless you knocked something loose in the engine compartment. Double check any areas you worked on to make sure nothing got dislodged. Scan the computer for codes and double check the air...
Check fuses for fuel pump, ignition,etc. If they're good, check for actual spark and fuel pressure at the engine. If you don't have both spark and fuel, it will not start. If you have no fuel pressure, then a failed...
Hi. When a heater core fails, it usually fails by leaking coolant into the passenger compartment in the vehicle. If your problem is that hot air is not being blown out of your vents, you could have several other issues....
There could be several causes as to why your car will not start. Unfortunately without more information, it is difficult to narrow down all of the possibilities to just a few. Some of the more common causes I have encountered...
You need to take it to a different mechanic to have a diagnosis. You either leaked out the refrigerant or the system was overcharged. Have the pressures checked. The sealer will not seal a leak in an evaporator or a...
This could be an ignition coil that may be starting to fail, but is more prevalent in the cold weather or rain. Generally, this is common when the coils begin to break down and heat cycling occurs, however the opposite...
Measure engine compression. Check intake vacuum to get an indirect indication of whether valves are sticking or not. Check base ignition timing and advance function and, finally, look at secondary firing patterns on an oscilloscope to determine if the issue...
It might be the idle air control (IAC) valve/motor. Inasmuch as the noise briefly continues after shut down the cause is not mechanical in nature but rather is in an electrical component or something involving movement of air. The noise...
