Can the manifold gasket cause your car to cut off sometimes?

Question

I've been having trouble with my jeep cherokee. It's been shutting off for no reason,but not all the time and it's shaking alot.

I had the distributer cap and spark plugs replaced,had a map sensor,and a couple of other things done,but that wasn't the problem. I thought it might be the fuel pump,but I had the mechanic check it. he said it's fine. I know its not the battery.

Answer 1

I take it that shutting off means stalling out and shaking a lot means misfiring. If this is correct, then yes this can be the trouble if we are talking about an intake manifold gasket leaking air into the intake stream without being monitored or controlled. Generally, these things can be detected by spraying an aerosol fluid that has a low flammability around the intake area. If the fluid finds its way into the combustion portion of the motor, the way the motor runs should alter. I am unsure about your problem though!! Usually when an intake manifold is leaking vacuum there is also a complaint of a high idle, especially when cold and I don't see that complaint here. Stalling and misfiring motors can be simply a bad spark plug, plug wire, or any other component leading to one or another cylinder. More diagnosis would be required to be sure of the problem here before dis-assembly!!

Answer 2

have you sprayed starting fluid around manifold gasket to check for leaks ? if it is leaking it will cause problems, but the biggest thing that causes what you're describing is either the spark plugs need changed and or plug wires, distributor cap and rotor. in other words probably just needs a tune up

Answer 3

a bad intake gasket can cause this to happen on occasion,but you might need to have it checked out really good before any money is spent on it,,a lot of times what seems like the problem,wont always be it,,good luck,hope this help,s.,,have a good x-mas.

Answer 4

Camery- What have they fixed? understanding it takes 3 issues to make an engine run. (gas, spark, and oxygen) with out one among those the engine received't proceed to be operating. i am going to provide you with somewhat record, enable me recognize if this stuff were replace (you may e mail me later) gas filter out, air filter out, hoses, spark plugs and wires. it is all i am going to imagine of today. yet enable me recognize if the mechanic has carried out some thing with any of those. (rather worry capturing)

Answer 5

if its a intake leak,then its loosing vaccum.that will make it run rough and hessitate.

Answer 6

possibly

Answer 7

no
