Car missing when driving a slow speed

Have you had the vehicle scanned for codes?

Once you have the codes, you can look them up on the web. Just do a search ' 94 Lincoln town car code.....' Just plug in the code(s) number.

well do a tune up on engine if missing.replace spark plugs and wires.replace distributor cap and rotor.replace ignition coil.clean fuel injectors and replace fuel filter.if all fails. if engine has high mileage could have low compression due to worn cylinders burned valves. do a compression check see condition of engine.vacuum leaks and leaking egr valve cause engine miss.

See if the port going in to the intake from the egr is blocked, the port is big on the egr end and goes down in size and can clog.

You need to diagnose the issues, to find
out what to do about the EGR System

It sounds like the same issue I just had. Check your EGR valve and insure it's working. Also, there is a tube assembly on the bottom of the EGR valve to the exhaust manifold. My Lincoln had a flex tubing between the fittings and cracked. The new ones are rigid. Another good sign it's the EGR is a gas smell. Hope this helps...

Have you checked your timing belt or chain?

You could try checking the EGR valve to see if it is dirty. It may be running badly at high speed also as it's harder to hear misses at high rpms. You should be able to tell by your acceleration and gas mileage also. Timing chain problems sometimes show up like this. Sorry I can't give you anything definitive but hopefully this will help a little. Good luck!

A FAULTY FUEL PUMP.IDLE SPEED TOO LOW.A STUCK OPEN EGR VALVE AND PVC VALVE.YOU WILL HAVE TO DROP FUEL TANK TO REMOVE FUEL PUMP.

Most common cause of stalling for Lincolns in that era is the TPS (Throttle Position Sensor). It regulates fuel mixture, idle speed etc. A bad TPS will usually act up in one of two ways:

1. When cold, car continually stalls
2. When warm, car stalls when slowing down (especially if AC is on)

As far as valve cover oil leak, it's a problem that should be addressed to keep oil from fouling your spark plugs but highly unlikely to be the cause of your stalling problem. Hope this answers your question. All the best.

More than likely a fuel problem. Try the fuel filter or check pressure from the fuel pump. If it misses at higher rpm it coiuld be spark plug wires or plugs.
