1988 240 Cold start problem and no go on acceleration

Post by mwhisten »

Two issues maybe related?
When cold, starts right up but crazy misses, engine shaking like mad. Eventually smooths out.
After driving for a while, give it gas and nothing happens, no acceleration. Doesn't miss or back fire.
Let off gas, idles smooth, give gas and nothing...

This suggests too much air entering intake manifold, and/or, injector o-rings need replacing, and/or, an injector(s) is/are not fully atomizing.

Check to see if in-tank pump is working....check fuel rail pressure.
