My 1997 Ford Escort has an engine problem.?
The number 3 Cylinder is not firing correctly. The plugs, wires and coil are new and work fine, the fuel injectors work fine, compression builds up in all four cylinders. My mechanic said that the number 3 Cylinder probably doesn't get a correct signal from the PCM (ECU). And he advised me to buy a new one, since they are quite expensive I would like to hear multiple opinions before investing that kind of money in a car that's worth hardly twice the price of the repair. Thanks!!!
Thanks for the answers so far.
It's the 2.0 Liter (US). They told me that the cylinder itself is ok, but I don't know if they just want me to do all kinds of repairs to make a lot of money. I don't want to spend too much on this car, since it is old and has 163,000 miles on it.

It could be a valve that gets stuck and is not closing properly. If all the cylinders have compression. They always tell you to buy the PCM then it turns out to be something else . That’s how some cheating mechanics make their money.

at a dealerships, they can flash the PCM again to see what is the issue.
Could be a piston ring damage, you might need to replace the piston assembly on the third cylinder as ford dealerships are notorious for not having component level servicability and only full assembly. either that or do a re-honing of the block bore.
is it a 1.6 liter gasoline?

you could go to the scrappys and buy another ecu (make sure its exactly the same model), fit it, and see if it makes any difference.
