A shake at higher speeds can be caused by numerous different things. This could be caused by your engine running badly, out of balance wheel, or even loose suspension components. My best recommendation would be to have your entire vehicle...
Question
Would leaking exhaust manifold throw a code?
If the exhaust system is not air tight, that will skew oxygen sensor readings and a consequence is a false indication of catalyst efficiency. In addition, the upstream sensor will not be providing a valid reading to the computer insofar...
Question
RPMs drop and car shakes?
Hi again Jarod. What you're describing is often a sign of a vacuum leak, exhaust leak, fuel restriction or faulty mass air flow sensor (designed to help mix air and fuel together). To be honest, there are more than a...
Question
Would leaking exhaust manifold cause truck to have vacuum leak?
The exhaust and intake manifolds have no connection. Therefore, leaks in one do not affect the other. The only "indirect" issue that might coincidentally implicate both manifolds is if the cylinder head were so warped, or damaged, that leaks developed...
Question
I have a 2000 Dodge Durango my ac compressor went out. Now there is light white smoke coming out the tailpipe. Is it due to the ac
If the refrigerant in the A/C system leaks, that refrigerant can't get into the exhaust system. White smoke in the exhaust is typically due to engine coolant leaking into the combustion chambers and such a leak could be due to...

Question
Is unplugging MAF while engine running a good way to test it?
Hey Jarod. Thanks for the question tonight. Yeah, when you unplug the MAF sensor it should stall the engine automatically if it's working correctly. If it doesn't stall, the MAF is likely damaged.
Question
Is a AIR TEMPERATURE SENSOR the same as a MAF?
Hi Jarod. Good to see you again. The ambient air temperature sensor and mass air flow sensor are not the same components. The MAF sensor measures air intake into the engine so it can adjust the fuel trim to be...

Question
My Dodge Ram 1500 4.7 stalling at stops sometimes
To pinpoint the cause, a diagnostic decision tree is used by mechanics and all components on that "tree" must be directly tested. As components are ruled in or out during that testing, one just proceeds along the tree. That is...
Question
Would coolant leak out of timing cover?
Coolant should not be leaking out of timing cover. You most likely have a water pump or hose leaking. The cooling system should be pressure tested to isolate and locate the leak.
