..Hello everyone. I've been lurking without posting for a long time now but now I've got a problem with my mostly stock '77 bug.
..So here goes: My daily driver runs great up until one day almost a month ago when I parked in a garage at work on a washout rain day, several hours later I come back out to go home and discover that I'm in a bad spot and that there's been a niagara of runoff from the ceiling washing right down into the engine compartment. Since then, it won't run on all cylinders at anything under about 2000 rpms. I run a fuel pressure gauge and an exhaust mixture gauge and it looks like the FI is running constantly too lean unless I'm using full throttle. Out on a highway, I can still blast along at 80 mph without any apparent problems but at lower speeds, I'm constantly struggling to keep the rpms up to keep it from quitting on me. My other problem right now is that it's winter here in NY and I've got my son's Accord torn apart doing an engine replacement in my garage so whatever I do to my bug right has to be done outside. I'm a fifty something old fellow who can't bring himself to spend a lot of time working on this FI system while I'm freezing my butt off in the dark.....lol
..So what's the verdict? Running too lean I think at low throttle because? In the past my air/fuel mixture gauge has given me a good sense of what normal readouts should be expected and now I'm looking at an all the way lean reading under all but full throttle and It dies almost immediately at idle. Normally at idle, the mixture runs a little on the rich side.
..Anyone who knows the '77 Jetronic system besides Speedy Jim out there? Where is Jim anyway? Hope you guys haven't got rid of him......!!!!!!!!
