The 335 and 340 codes are for crankshaft and camshaft circuits. This could be bad sensors, or it could be an issue in the wiring to the sensors. The 421 is for a catalyst performance. It can come up because...

Hi Paul. Thanks for sending the question tonight. To be honest, when wholesale replacement jobs like you've described are completed, multiple issues can be missed, incorrectly installed or even have compatibility issues that can lead to a vibration. If you...

Any hoses that would connect to a throttle body are either going to be for coolant or vacuum. In order to determine where the hoses go from the throttle body, I would recommend following them with a flashlight and or...

The term "short circuit" is probably the most overused term in technology, but I think it might apply in your case. It sounds like there is some connection or device that is shorting you battery and charging system to ground...

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...

You will need to have the number one cylinder injector tested to see if it is getting signal from computer and cylinder compression to see if it has an internal engine problem. Then if these are okay then will need...

Hi Ester. Thanks for contacting us today. The first step in diagnosing a problem like you've described is typically tracing and verifying electrical connections that engage the starter. This would begin with the car battery, followed by ground wire connections...

Hi Renee. Thanks for contacting us today. The Shifter Position Switch and Neutral Safety Switch are one in the same, but I don't think that's the source of this type of problem. Typically when that component fails, it causes all...

This is an electrical malfunction and is what is referred to as a "global" malfunction. That means a principal circuit, or circuits, was interrupted obviously on an intermittent basis. Battery terminal corrosion is possibly implicated at least as a contributing...

P0401 (https://www.yourmechanic.com/article/p0401-obd-ii-trouble-code-exhaust-gas-recirculation-flow-malfunction-by-jay-safford) will often set if the passageway from the EGR valve to the intake is blocked with carbon.

The flashing check engine light signifies misfiring and the engine fault(s) causing the misfiring are probably related to the loss of power you are describing. Misfiring is potentially very damaging and so you should drive at a lower speed to...

Hi Deshawnda. Thanks for contacting us today. Although some "mechanics" recommend using a liquid head gasket sealer, the truth is that 80% of the time - it doesn't completely do the job - or it causes additional problems. These sealers...

Hi Dyani. Thanks for contacting us today. It really depends on what type of noise is being produced when shifting which will determine the root source or cause of the noise. If it's a grinding noise when your automatic transmission...
