My 91 Max VG30E SOHC has been choking (hesitating) at 55 mph and above on the highway lately, like its clogged or something. Scared the ((*(*&& out me, because it feels as though it may cut-off, also I noticed that at certain times when I depress the accelerator I hear something like an exhaust leak that's very loud. I can hear it in the cabin so I know that noise is coming somewhere from the front. Any feedback is much appreciated.

 

pop the hood and look...

 

everything looks good to go....vacumm lines, MAF etc.

 

r u sure its not vacuum...wat type of sound it is? like whistle sound or yelling sound? lol sorry dont know how to describe....

 

Is there a way to test my MAF on the car?

 

didja look at all your EGR components?

 

your cat could be plugged

 

had the same problem on a grand prix, turned out to be the cat. the car ran so rich from some other issues that it kill the cat. but checking the egr is a good idea to be on the safe side

 

Guys,

I replaced my MAF and the problem went away. Replacing the MAF also cured a slight idle problem that I have had for sometime.

 

good...i replaced mine too two days ago i got it from junkyard for free...my problem was gone...
