You dont need to ground your ht lead, infact that could damage your ignition system, if in fact removing it from the plug does make it worse you then know that this cyl was firing and that ignition on this particular cyl is not your problem.

1998 dodge ram 1500 v6 idles rough


Intake gaskets may not be sealing well causing vacuum leak and lean idle miss.

My 98 Dodge Ram 318 4x4 stalls at when I come to a stop only when it is at operating temp. It starts back up right away. It does not do this cold and always runs good down the road.


Yank the TB, pull the IAC valve off and clean it and the TB really good. It is a common problem and cleaning the TB fixes it. IIRC - there is also a very small air passage that can get plugged, also causing problems with the idle.

While you're in there, look down the intake at the bottom and see if there is any oil pooling in the bottom of the intake. If so, you have a leaky plenum gasket and it should be fixed. Causes pinging, poor mileage and oil loss.

Dodge ram 1500 5.9 idles rough and stales out


This truck has problems with the cover inside intake leaking vacuum and causing rough idle and oil usage , its hard to say what your problem is with out testing, have you had the check engine light scanned for codes? what year is this dodge?these also had intake leak problems. try starting the engine and let it idle and then with some carburator cleaner spray around intake gasket and see if idle changes if it does then you have a intake gasket leak, another problem may be a leaking injector, try some sea foam in the gas tank and run a half tank of gas and see if that helps, otherwise a fuel injection system cleaning would be the way to go but this is only if its an injector problem, if this truck is 1996 or newwer have the computer scanned at an auto parts store for any codes. if there are codes let me know what they are even list the code and #. good day

2001 Buick Regal keeps stalling and running rough has white smoke coming out of tail pipe


The upper intake plenum is leaking coolant into the cylinder heads. The head gaskets on this motor are awesome. So, chances are it's the upper intake plenum. You can check this, by removing the vacuum hose that runs between the upper plenum and the brake booster. Stick your finger in and try to touch the top of the lower intake manifold. If your finger is wet it the upper plenum. You might as well replace the lower intake gasket while you're performing this work because they are prone to failure also. Use a shop vac to pull any coolant out of the cylinder heads. Get brand new spark plugs because the old ones are probably fouled. Once you get the plenum and gaskets replaced, remove your fuel pump relay and leave the spark plugs out and turn the engine over repeatedly for about 10 seconds to push any excess coolant out of the cylinder heads. Then, put the spark plugs in and turn the engine over for 10 seconds again. This will burn excess fuel as coolant out. Then, replace the fuel pump relay to allow fuel to be pumped into the heads. Car will smoke for a few when it fires up, but will clear out quickly. CHANGE THE OIL! Twice within a week if possible.

I have a 2001 dodge ram 2500 with a V-10. It has started running rough at low speed and ideling at stop lights. It does not stall just runs rough. It was just tuned up in June 2010. There are no warning...


Did you replace the Fuel filter? Have you checked for Leaky Vacuum hoses or bad Intake gasket.
The easiest way to tell if it is a bad vacuum leak is to spray Carb cleaner while the car is running at idle around the intake gasket and throttle body . You will find the leak once you spray a spot and it idles better.
Please leave me a good feedback on here.
