PCM Problems

[mrviper99]

How many guys have had problems with their PCM's for 1996-1998 year vipers. I'm trying to track down a lean fuel problem and trying to see if the PCM's could be the problem. Thanks

The most common "lean" fuel problem was actually a intake manifold gasket leak, especially on the 96 & 97s. Could you be a little more spacific? I don't think that many PCM's had problems. Some needed program upgrades for certain problems.

Hi Jim; 1996 GTS has cam, heads, 1.7 rockers, headers and VEC 1 engine runs good except when I jump to WOT. The a/f meter shows it go lean the car boggs the 2 seconds later goes to rich and car flys. Does this in all gears starting at 3200 rpms.
