Hey guys I'm new here. my dear friend just lost her husband and son last month so she was left with alot of cars and other debt. This grand national is one of them. Has 80k on it and is almost mint. 10 years ago he bought this car and it seems to cut out very bad under boost. Well it has sat till today. Got it started and drove it home to try to fix the cutting out problem. It runs and drives down the road perfect and also setting it park it will rev to redline fine but when ya hammer down and the boost come up it will start cutting out at about 3500 RPMs and will not rev higher till ya let off and let the boost drop. Just trying to help her out with all her cars because she has to sell them all to pay for both funerals. Anybody ever heard of this before? This one has be baffled. It also lost the power brakes but just got that fixed. stuck pressure sensor. thanks in advance for any help.
