Ok, second drive started off fine, oil light no flicker when she's cooled off..
Sounds: 1. Lean 2. Over Advanced How many clicks off of black smoke is your mixture set @? It feels now like it wants to be shifted just under the power curve, and it pings in a 200 rpm range starting at 3k. Maybe I can string together an a/f meter from paperclips, and dustmites? I hope the oil flicker isn't bad bearings... (IMG:style_emoticons/default/blink.gif) 62 miles isn't better than 4800.. M |

Sure it will work but rich. The MPS's were calibrated for each run of motors. 037's (last 3 digits) were for the 73 2.0L cars only. Put them on other cars and they run rich. 049's are what go on 1.7's as they are set leaner at partload and WOT.
Usually, someone puts a 1.7L MPS on a 2.0L car and runs it lean. The result can be the dropped seat problem but you will get better gas mileage! The MPS's are pretty sensitive little things and handle the A/F mix by sensing the engine manifold vacuum and then adjusting the injector duration. Actually, people drive within a narrow range- partload which is cruising along at 3000 rpms at 35 mph or WOT. Geoff |
