replace timing chain
Starts hard then it rough idles for a short time then smooths out but when you give it gas it miss fires and bucks and does not smooth out.
sounds like the timing is off
Sounds Like You Are Out Of Time. Most Likely Timing Chain.
Motor mounts are bad
Mine did this and I found out it was the timing belt that needed to be changed.
check your timing & up your idle a little
Check timing. idle could also be set too low (rpms) so vibration is increased.
Timing belt could be bad and could have jumped a tooth or you need a toon up.
Rebuild it. If it's a 97, it must have close to 150k miles.
I have 1998 a Lincoln town car with the same problem.. It idles rough when you start, then smooths out once it warms up and you give it gas. From what I am reading its either an oxygen sensor or you have vacume leak in one of your hoses by the manifold.
I'm not a pro but sometimes the timing can be off, if it idles higher than it should out the gate, that can do it. That's all I got...good luck
typically if the motors idles and revs, but dies under any kind of load (put into gear) then you have your timing set wrong. you need to use a timing light and make sure that it is set correctly before and after the timing advance. that would be the place to start.
My 1990 idles at about 850 and with the ac on 1100
idles at 3000 will not go down 1993 grand prix gtp

hi sounds like it could be a vacumn leak or double check cam timing. jerry
I would say that the timing is off, if it has distributor and not coil packs try to turn the distibutor some.
hm....try checking your ignition timing (or getting a mechanic to do it) with a timing gun. Also try checking the EGR Valve
a/c blows warm air when idles cold when running
Matinee Idles - 1922 was released on: USA: 4 September 1922
check the timing belt. or on the 1996-1998 the crankshaft bolt comes loose and shears woodruff key in crank shaft.
I am not a pro, but mine broke the locating pin on the cam pully, which altered the cam timing. Luckily the valves do not touch the pistons! The engine was pulled and ready for rebuild when it was found. I rebuilt it anyway.
crankshaft sensor going.
It could be a dirty air filter or a dirty throttle body.
