Cylinder #2 Misfire-after intake manifold replaced

I had my intake manifold gasket go at 130k miles and had a friends cousin replace gasket, after this repair my #2 cylinder is misfiring. Prior to this my truck ran great. Could this be something he inadvertently did on the repair? And what is the proper way to troubleshoot the problem and possible problems that could be causing this misfire?

It's possible he has two plug wires crossed, or pulled a spak plug wire apart replace #2 spark plug wire First. To test check the firing order and make sure all the wires on the right plugs and the correct place on the distributor, if it is right, then buy a can of carburator cleaner and spray around the intake gasket if the engine revs up when you spray the carb cleaner around the intake manifold with (engine running) if the engine rpm revs up you have an intake leak.

Obd indicates vaccum leak causing misfire on cylinder 2


Bad spark plug ignition coil's do that too. Cheaper. $50. #2 cylinder is the middle one on the rear bank which is closest to the firewall. You'll need to take off the top intake to get to it.

Stalling and running rough - Hyundai Elantra - 2001-05


The Hyundai Elantra 2001 - 2005, 2.0 L engine is noted for this problem. It will lack power on acceleration and run rough and stall while driving. The engine light will come on for misfire codes. This problem is caused by a vaccum leak at the intake manifold gasket. The gasket is broken and needs to be replaced.
To replace the intake gasket with a new one, remove the 12m nuts holding the intake to the cylinder head. Then pry back( note: you do not have to completely remove the intake manifold here) the intake manifold to gain excess to remove the old gasket. Remove any excess gasket and clean with brake cleans the surface area of the intake. Install the new intake gasket on to the head and carefully install intake on to cylinder head studs. Tighten up nuts gradually and evenly to 15-20 ft.lbs.

On a 3500 dulley 4x4 big block chevy gas engine, I have a cylinder 8 misfire and engine light. It also had a mass aire flow indication but that was replaced. only 86000 miles on 03 truck


Check the intake manifold gasket. If it leaks it will draw air into engine and this air bypasses the mass air flow sensor which will cause a rough idle or running symptom from running too lean. If you change the intake manifold gasket you should probably change the valley pan gasket at the same time. A dealer will change both for less than $500 and you might save some more if you dig around on GM Service website and find a coupon discount (Usually 10%-20%). You might save more at a local shop if you trust them and they do this type of work. Getting to the intake manifold gasket also exposes the valley pan and since you are already there it only takes a little more to change that gasket too. Some GM V-8 engines use a little oil between oil changes and if both gaskets are meticulously changed at the same time it will sometimes fix the oil usage. It did for me on my Tahoe (126k miles).

P0302 is random misfire on cylinder #2.

Most comment cause is vacuum leak at the intake manifold and vacuum hose.

If you valve cover is leaking oil on then DO THE HOLD JOB.

Remove valve cover to gain access the intake manifold.

Change the intake gasket and valve cover gasket.

Sound like an air / vacuum leak to me.
Re-check for an air leak on #2 cylinder inlet manifold.
Use a propane torch (unlit, of course) to flood propane gas around inlet manifold/head flange & gasket area.
If there is any change in idle speed during this test you have a vacuum leak.

My 99 Dodge Ram 1500 I just purchased high oil consumption


It could be burning and you don't notice. Remove air filter box assembly from top of intake manifold. Hold throttle wide open (engine off) and look through throttle body (flashlight may be required) and see if oil is puddled up inside manifold. If so then the intake manifold will need to be removed so the lower pan gasket can be replaced.
