If you have blue-gray smoke coming out of the exhaust, then you have worn or damaged piston rings, or valve seals. If the smoke is excessive, a major engine overhaul will be necessary. If no blue-gray smoke is coming out of the exhaust, then look for a worn/damaged oil pan gasket, or a loose oil pan plug, or a loose oil filter. In either of these cases, you should see oil spots on the ground under the car.
i would like to know what would cause the miss firing in Chevy Malibu
frozen pulley
bearings
There can be several things that will cause your 2003 Chevy Malibu to run rough and not shift into fourth here. The probable cause is a lack of fuel. Due to a bad fuel injector.
YES
Yes, and that will cause shifting issues.
Rods and Rocker arms were the problem with my Malibu after changing lifters
First thing to check is the pcv valve.
A bad cylinder head gasket.
You can tell if the transmission, in your 1998 Chevy Malibu, is going bad. If there is a whining or clunking noise. The transmission might cause your engine to install when you are stopped with your foot on the brake.
Check the Malibu crank position sensor and coil pack. One of these is the most likely cause of the loss of fire.
A faulty crank sensor would cause no spark and no fuel.
