Yowsa! - many small problems with running on '90 SPG w/ EGR.
Am I correct in hearing that this was a problem combo, this year only?
Do the 91-92 Turbo's have an ECU that will work with my system with the EGR removed? I need to solve problems and maintain DEQ inspections.
Car will hardly start if temp is below 50 degrees, when it does start it runs extremely rich - barely runs. Once run for e few minutes it runs fine.
If temp is above 60 degrees it starts and runs fine.
When running and driven I get off and on of 'check engine' seems to relate to RPM up above 3500 then down - light comes on as RPM's drop past 2000 and then goes out after 30 sec at idle.
I also get occasional 1900 RPM idle and very slow RPM drop to idle, occasionally while slowing to a stop and engine does not slow below 2200 RPM.
Bentley seems to have no info on EGR system.
I'm very familiar with LH 2.2 but just beginning the learning curve with this system. Leads as to where to learn greatly appreciated.
Bob
