HI folks. Not trying to fill your inbaskets, but you all seem to enjoy the repartee. First, thanks for all your suggestions. Long day of trying things, in parking lot of Ramada Inn, with some progress, but ultimately not successful. While I'd love to fix this myself, may limp to a south florida garage in the am if I can find one. My own next step would be to test fuel pressure, maybe a complete drain of the tank, and a new fuel pump? I still feel like I am fuel starved. I do have a couple of questions though. Should I have a crankcase breather hose leading to the air cleaner in my 91 GL? I do not seem to. Given I've been fiddling all day, is there any kind of 'reset' necessary, to Clean memory or anything like that. I did not touch the ecu. Todays efforts: - checked idle stabilizer - humming, re/re control unit to clean contacts - adjusted throttle position switch to spec for idle - new fuel filter - previous one was 3k old, but was installed backwards when I looked it. Lots of crap came out - distributor/wires, checked all connections including hall, confirmed spark - pulled off all engine compartment grounds, cleaned and tightened - pulled and cleaned contacts on 2 temp sensors - disconnected o2 sensor - some other stuff I forget Current status - starts very rough, sputters, and misses, but I can now get revs up eventually, and once at operating temp, will idle roughly at 900rpm, And accelerate roughly to cruising speeds, in other words I am sort of mobile. Once engine turned off, a restart, even immediately brings the same sputtering/missing, and eventually smooths out somewhat. Next steps?

So, I checked a few things. -idle stabilizer control unit contacts are clean, no moisture -Idle control stabilizer valve is humming. -throttle valve switch is NOT working at idle but working at full throttle -WHEN HARNESS IS REMOVED FROM AIR FLOW SENSOR THE ENGINE IDLES SMOOTHLY. When the harness is reattached it drops revs 200k, and gets very rough and stumbles badly when throttle applied. Does this tell you anything. Can I drive it with the afm unplugged?

Help needed. We are stranded at Homestead, Florida, where Hwy 1 heads into the Keys. 91 GL Westy doesn't want to go any further. Started rough this am, but ran decent most of day once completely warmed up. Just completed 1700 trouble free (till now) miles on new fuel injectors, fuel lines, plug wires, plugs, cap and rotor. Fuel filter has about 2-3k on it. Checked plugs this am, and they were a brown and dry. Now just fueled up, and will start, but spits and burps, and can't get all cylinders firing on start up. Feels like a lack of fuel delivery to me. Getting more and more rough on start up last couple of days, actually since some heavy rains a couple of days ago. Suggestions on root cause or things I should check please, and does anybody know any techs around very south florida that I could track down??? THANKS. Mark & Mary
