yes it can
Yes, an intake gasket leak can cause an engine to run rough. This leak allows outside air to enter the intake manifold, leading to an incorrect air-fuel mixture, which can result in misfires, rough idling, and decreased engine performance. Additionally, it may trigger diagnostic trouble codes, further indicating issues with the engine's operation. Repairing the gasket can help restore smooth engine performance.
Yes it will cause it for sure. You will get DTC of P0170/P0173. Car will drive rough.
Probably just a leaking intake gasket. When it's surging, try pressing downward (with most of your bodyweight) on the intake. If it settles out you need to replace the intake gasket.
That is a very common problem with the vortec engines.You will have to replace the intake manifold GASKET. If you run your finger around the 4 corners of the intake were it sets against the heads you will probley find the leak.Have you run the engine HOT or over heated it ? If you did then you may have damaged the head gasket / gaskets and that would cause a rough idlel.
I blown head gasket can cause an engine miss which one cause a rough idle.
Yes, a leak in the intake manifold can cause spark plugs to misfire in your 2001 Ford Crown Victoria. When the intake manifold leaks, it can allow unmetered air to enter the engine, leading to a lean fuel mixture. This imbalance can disrupt the combustion process, resulting in misfires. Additionally, a vacuum leak can cause rough idling and poor engine performance, further contributing to spark plug issues.
Had the same problem with my 2003 Axiom... It was my intake gasket. 50 dollar gasket.... easy fix
replace the leaking intake gasket...?????????????need more info replace the leaking intake gasket...?????????????need more info --------------------------- The '00-'02 SOHC s-series have been notorios for leakin intake manifold gaskets. Symptoms include a SES code P0301 -304 (misfire codes) along with rough and high idles. A simple test will show if this is the problem. Using brake cleaner with the car on, spray around the gasket at each cylinder. if the idle changes then you have found your issue. FOr a how-to procedure with pictures email/message me.
Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.
you need to make sure your plugs and wires are ok, if it is still rough 9 out of 10 chances it is your intake manifold gasket.
If you know the spark plugs and wires are good, then check for a vacuum leak. The vehicle is 11 years old, and you may very well have a crack in a vacuum hose. A leaking intake manifold gasket will also cause rough idle.
Check the Park Avenue EGR valve for a clog. A clogged valve can cause a rough idle and stall at a light.
