I have an '88 Cavalier Z24 with the cowl induction. It's a 2.8 multiport 5 speed and I think it's kind of a dog. I know it's only a
2.8 but it's also a very small car. Being a convertible may make it somewhat heaver. I do have the EGR vacuum line disconnected, as it seems to run better that way. I haven't replaced it because it doesn't have the original engine in it, and there are two different EGR's available for it, depending if it's an automatic or stick -- and I don't know which kind of car the current engine came out of. As a new EGR is expensive I can't afford to buy one without knowing if it's the correct one or not, nor if that's the reason if it doesn't change the performance. It has had new heads about 20K ago, along with plugs, wires, etc, sounds good, idles smooth, etc. and gets 28 mpg on the highway -- it just seems like it should have more power. Would putting a K&N air filter on it give me any appreciable improvement? Also, would it sound any different (you can hear the induction noise thru the cowl -- would that sound be any more pronounced)?.- posted
