Live Chat: I have a 1995 dodge Ram, v8 magnum, recently it started to sputter alot while driving, if you drive for about 15 minutes it will start dropping rpms and speed and sputter really bad, if you let it sit for about 30 minutes its fine, it has all fluids and gas….does anyone know any possibilities for what it might be?
I really need some help and answers to this problem.
It sure sounds like you have a problem after the truck gets warm. Usually this is either an ignition component or a sensor problem. Possible items could be a faulty ignition module, a bad coil, ignition wire, etc. Sensors that usually get affected by heat are crankshaft sensors, cam sensors and the like. A scanner would come in handy here if you have one or can get one.
During a test drive, you can watch the live data on the scanner and when the truck starts to act up you can see which component is dropping out or having trouble. Without that, I would at least recommend getting it scanned for codes to see if there are any and that can help in diagnosis as well.
OK. Thank you for your great information on this problem with my Dodge. I will look into those things.
Hello. Can a bad gas cap cause your truck to fail the EVAP test on my vehicle?
Do you mean the state emissions test?
Yes. Most states test the gas cap. If it is not sealing properly, this has the potential of setting a check engine light and codes. This will can also cause fuel vapor to leak to the atmosphere, so the Federal Gov. emissions standards sill make a car fail.
