Runs smooth then runs rough & rough back to smooth running.


If your check engine light comes on get it checked. To me it sounds like an engine misfire probably cause by a coil pack or spark plug wire going bad. The misfire should cause the check engine light to come on maybe even flash if the misfire is bad enough

1998 Chev 1500. 305 T.B.injection. Engine runs a little ruff when first started hot or cold but smooths out perfect after about 10 min of running. Check engine light on.


If you haven't already changed plugs and wires, do that first, but i suspect you have an intake gasket or a head gasket leaking. It runs rough when you start it because of coolant in the cylinder. After it clears out and dries, it will run fine. That would especially be the case if you have to add coolant occasionally.

2001 mazda tribute v6 runs rough cold ildes at about 200 rpm till it warms up then its ok what could it be


I replaced the upper & lower manifold runners seals, now it runs perfect, The reason it runs ok when warm is because the manifolds expand and seal the gaps on the surfaces that the worn old seals are not closing. Also change the spark plugs.

My truck when I start it on very cold mornings run rough until you let it run for about ten to fifteen mintues. Then when the weather is warm the truck runs fine. It also has under 69,000 miles.


Count your blessings that it starts. It sounds like the cold air is affecting the idle mixture. Check the hose running from the manifold to the air box to see if it is intact. If not, replace/fix it so that you pull warm air in as soon as the engine heats up.

Runs rough, lags, and will backfire if I push it


This is probably one of four things or a combo thereof...dirty fuel injectors, cracked distributor tower/burned points (if it's not electronic ignition), burned valves or air/gas flow sensor if it's computer controlled (the chip is likely bad).
