Hi guys. I need some help. a buddy of mine has a 200 sonoma with a4.3 v6. recntly it has been having problems. according to him he has changed the air filter, fuel filter, fuel spider, fuel pressure regulator,.... anyways I went and looked at it today and it will start right up. (After jumping the battery. it has been sitting for 2 weeks.) it runs okay at first but in park if you rev it up to 3500 rpms it has a stutter almost like a miss. When you put it into drive it bogs down like crazy and pops through the throttle body. we drove around the neighbor hood and ended up having to tow it back to the house because it cut off when stopped . Any advice on this matter would be greatly appreciated.
Thanks in advance... Kraig
