From what I have seen, most of these things suggested do not match up with my symptoms. When I slowly depress the accelerator, it runs great until it reaches 1400 rpm's. It then falls on its face. If I let off the gas, it drops below the 1400 mark and then runs as good as it did before it cut out. These circumstances haven't changed it does it every time that I push on gas. It does the same thing in drive, it just cuts out about 10 mph and also picks back up as the rpm's drop. How do I build the code reader I read about in one of your replies.
