My 98 GT only smokes after it hits a certain temperature after that it smokes out of the tailpipes.If it's cool out it will run all day with out a hint of smoke,going crazy trying to figure this out.TIA.

 

Holy smoke over 130 veiws somebody help me please getting ready to shoot this horse.

 

Hold your fire Al. You have a tough one. The smoking is affected by the weather? What color is the smoke? Are there any noises or is the CEL coming on?

 

NO just the temperature as soon as it reaches the same spot on the gauge.white smoke if i open the egr by means of straight vacuum it stops instantly.

 

Bad EGR increases emissions. I'd replace it. The picture provided at the below link about symptoms of a bad EGR Valve is of a tailpipe emitting white smoke.

Increased Emissions
The EGR valve's main purpose is to aid in the reduction of noxious gases produce by the engine. It does this by lowering the temperature of the combustion process through the introduction into the combustion chamber of controlled amounts of exhaust gases. This lower temperature has the effect of reducing the amount oxides of nitrogen (NOx) produced by the engine. A faulty EGR valve will fail to properly cool the combustion process allowing these gases to increase, which can lead to an abnormally high NOx reading during emissions testing.

Thanks Vertigo GT Thats what the tailpipes look like i will have to get that fixed.

 

I hope that takes care of the problem.You nailed it with bypassing the EGR.
