Hi guys, sorry if this post has already been discussed. I am currently driving an old Ford laser lynx tx3 1997. Every time I take the car for a long journey or I accelerate on highway there will be a strong exhaust smell/engine smell coming out from the air conditioning. I already seal the vents or possible holes but the problem still persist. The workshop stated I might need to take out my car dashboard and check or seal something. Is this true or is there a way to check. Is there any good or trustable workshop to fix this problem in PJ Area or even KL Area?
