Default 244 DL 1977 - running very rough

Hi Everyone

just pickup a 1977 244 DL which has been sitting for a number of years. Was told it ran when parked but very rough.

2.1 Fuel injected engine.

can confirm after cleaning out the fuel filter and purging the old fuel out of the fuel line we managed to get her to start.

runs very rough, almost like a cylinder is not firing, touch the acelerator and she dies. Did manage to get it to rev up and run at higher revs starting the car with my foot on the accelerator. But quickly died again.

when running it would idle very rough shacking all over, touch the accelerator it would die and backfire a little.

not blowing any smoke or making any bad engine noises or rattles.

Felt like its missing a cyclinder

i also noticed the coil was getting quite hot, which concerned me.

it has had new distributor cap and leads fitted
purged the fuel and cleaned out the fuel line of stale fuel

my next things Iím going to look at are:
firing order in case the leads have been installed in the wrong order.
look at spark for each cyclinder to make sure we have all 4 cyclinders with spark

any tips with these old engines?

First, take a compression test to eliminate things like rings, valves, head gasket, etc. Then go to to electrics, fuel, etc.

CIS cars seem to be pretty sensitive to air leaks from hardened injector seals. makes them run way too lean.
