I have a 1988 240 wagon. So far I had to replace the fuel tank and fuel sending unit, then coming home the timing belt broke(replace it with seals and WP), fuel filter. My problem, it stats and idles perfect, sometimes it acts like someone shut the fuel off, just loses power, this happens cold or warm. It happens when I am accelerating hard, if I pull my foot back it seams to improve but not much. BTW tonight I remove the TB and cleaned it. Also new flametrap. Could it be the fuel relay? If so where and how do I get to it(nothing is as easy as my 740 wagon). Thanks ps it has 164,000 on it.
