my engine is a 2.2 ecotec and does not have a vaccum operated fuel pressure regulator, I mean there is no vaccum line going to it.
so are these possible problems for just rpm jumping or also for smoke out of tail pipe?
could you mean under the valve cover, there is not an external pcv valve? There is hose going from intake to valve cover about 6 inches long, no valve at valve cover
one more question, could the pcv valve also cause it to run slightly hot when sitting at traffic light as well, because I have noticed that when sitting at traffic it runs just barely hot and then when I take off then comes the puff of smoke out of the tail pipe?
and the pcv valve would be causing me to burn coolant?
um not real sure, I know that when I am sitting in school traffic waiting to pick up my children I notice the temp gauge rises a couple of notches, but if i cut the air on it doesn't do it
