Hi, thanks for your question. It sounds like the starter bolts may not have been tightened properly or the starter could be faulty as a new part. I would recommend retracing your steps to make sure that the starter was...

Hi. It may be a compressor issue, or it could be an expansion valve that is a stuck open. A stuck open expansion valve would show a higher than normal pressure on the low side when the AC is in...

The catalytic converter may certainly cause the P0300 random misfire code to show up due to the inability for the exhaust to properly breathe, which can cause un-burnt exhaust gases to reignite inside the catalytic converter (https://www.yourmechanic.com/services/catalytic-converter-replacement). A clogged or...

Hi there. In most cases, bluish white smoke is caused by damaged piston rings, or damaged cylinder head valve guides and is referred to as oil blow back. I am not a believer in "stop smoke" products, as they typically...

First, we need to make sure the signal wire to the starter is properly connected and the power cables are attached properly. I have seen many situations where the signal wire is loose or the connector is broken and the...

Hi There, It sounds like you may have a couple of different issues. The idle problem may be a result of a dirty or faulty idle air control valve. The idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) monitors the air intake as...

The pipe that connects to the hose on the back of the engine is the supply pipe to the heater core. If you need further assistance with a coolant leak (https://www.yourmechanic.com/services/oil-fluid-leak-inspection), then seek out a professional, such as one from...

An internal seal failure in the master cylinder is possible and that is easily tested for by either blocking off the master cylinder ports and/or using pressure gauges to measure pressure developed within the system upon pedal application. It is...

The crankshaft damper has a broken rubber insulator and no longer turns the outside of the pulley moving the serpentine belt. The accessories are not being turned causing the loss of power steering, charging and any other accessory that is...

Hi. There could be a problem internally were the speed sensor (https://www.yourmechanic.com/services/speed-sensor-replacement) is reading making it still throw the code. There also could be a problem with the wiring harness or connector going to the speed sensors (https://www.yourmechanic.com/services/speed-sensor-replacement). The wiring...

This may be related to many different possibilities. I would recommend with first starting with checking the fuel pressure to be sure the pump is producing the proper fuel pressure. In addition to the fuel pump, there is also something...

Have the cooling system pressure tested to see where the coolant is leaking out? If timing belt was broken or installed wrong you may have bent the valves in the engine and should do a compression test to see if...

I would recommend having your vehicle's cooling system pressure tested by a qualified professional to determine the exact source of the coolant leak. This test will put your cooling system Under Pressure without the engine running to avoid the sound...

Hello - given your symptoms and mileage, the throttle position sensor (https://www.yourmechanic.com/article/how-to-replace-a-throttle-position-sensor-by-mia-bevacqua) is a likely candidate for this behavior. Check for problem codes first to verify the diagnostic code(s) engine management will provide automatically. Most auto parts stores will do...

The noise could be the serpentine belt (https://www.yourmechanic.com/services/serpentine-drive-belt-replacement) slipping due to age or the tensioner not holding the belt tight on the pulleys. Also an idler pulley could have a failed bearing causing the noise. Try removing the serpentine belt...

Hello - the Manifold Absolute Pressure (MAP) sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-manifold-absolute-pressure-sensor-map-sensor) is located on top of the intake manifold, in the middle. This will be between the valve cover and the firewall that separates the engine compartment from the passenger compartment. It's...

Hi there. A crankshaft position sensor will cause the engine to not start if the sensor has failed. The crankshaft position sensor is designed to tell the ECM (computer) when the cylinder number one is at top dead center and...

Hi there - manufacturers are using plastic for valve covers, intake manifolds, and other engine components more and more often for weight and expense savings. Unfortunately, with repeated heat cycles, some of these plastics become brittle, or warp and won't...

Hello. From what you describe it would appear that your vehicle may be experiencing possible mechanical or engine management issues. If these issues began after servicing the spark plugs and wires I would recommend verifying that the plugs are not...

The most straightforward possibility here is that the transmission range sensor (https://www.yourmechanic.com/services/transmission-speed-sensor-replacement) and the shift linkage itself are misaligned. The range sensor provides an electronic "here's the gear I am in" to the transmission controller, and other interested electronic components....
