Nathan,
I had some trouble with strange readings when I installed one into my 86 SPG, which is LH 2.2 but the problems could be similar....
I wasn't ever getting a rich reading at all... ever... and strange readings otherwise. The 2 problems were this:
The throttle position sensor was not properly set up, so that it didnt tell the ecu that i was at WOT when i was at WOT and the ECU did not richen the mixture... make sure that yours is properly set up according to the bentley.. this is very important. Even after I did this though, things weren't quite right...
I suspected the o2 sensor... but I tracked the problem down to a dead air mass meter, which i suspect many people on this board have but just throw more and more fuel at the engine to band-aid the problem. These AMM's do not last very long and usually require replacement after a few years... after I replaced mine, everything has been wonderful. I get a nicely rich mixture at WOT and everything reads like I would expect it to read. I run about 16-17max PSI with my 3.0bar FPR (with just a few other minor tweaks/upgrades) and I run plenty rich like that. Technically with a failing AMM, one could just force more fuel through the system to counteract the dead AMM... but why?
Good luck!
