This one has me stumped. On a cold start, my 97 D1 idles ok, but sputters and barely drives above 5mph until the engine is thoroughly warmed up, at which point it runs excellent like nothing ever happened! This issue wasn?t something that was slowly building up and running more poorly over time. It just popped up out of the blue. I searched this forum for a while and found no clues. Anyone else run into this issue or have any thoughts on a fix? Much appreciated.

Brian

I have the same issue and unplugging the MAF didn't help.

I would put a vacuum gauge on it and see if the needle jumps around when it's cold. If it does your valves are sticking. No check engine light?

I have seen failed coolant temp sensors cause issues
