my 1989 toyota corolla gts (AE92) has a light haze of smoke comming from the exhaust. it used to be really bad but i did a complete tuneup and buting new spark plug wires soon had to order them for an idle problem.but what could this smoke be from.it is a light white somke hard to tell cause the smoke doesnt come out alot anymore.thanks in advance for any help

 

Sounds like a blown headgasket if its white smoke. Could be a wide array of other things but id start there. How does the coolant and oil look?

 

oil was really dirty but look mormal but got changed yesterday and also the coolent is fine
