New spark plugs. Runs like ****. Ran fine before

get urself a can of carb cleaner...brake cleaner...whatevers clever
with the car running spray it over vac maf sensor...until you hear the engine bog down. now you found ur vac leak or anything else and leaking.

you changed the spark wires but did you change the plugs..and if its a carburetor check the distributer as well

usually a secondary ignition problem(coil pack, spark plug cables).

USING WRONG TYPE SPARK PLUGS. THE SPARK PLUGS TOO LONG.

have you changed the fuel filter, air filter, and dod you put new spark plugs in it when you replaced the coil pack?

sounds like spark plugs or spark plug cables are bad and it is in fact misfiring this happened to me in my car and my spark plug cables were bad

try tune up air n fuel filters, spark plugs and wires... should do better

have you had the catalytic converter checked?

Hi,
The air cleaner mighty be clogged causing insufficient air supply. That is why it runs fine on idle because less air is needed and when the engine demands for more air, there isn't enough.

If that is your only transportation you need to call other repair shops. Find out about towing fees and what diagnostic fees they have.

Before there were diagnostic scanners, there were Mechanics. Scanners come in all types and some will suggest possible solutions and others are tools which Mechanics use to find problems.

For instance, you are told you have fuel pressure. You are told they installed new spark-plugs. You were not told if the spark-plugs are getting electricity to fire. You were not told if the fuel injectors are getting electricity to allow gas to reach the cylinders. You can have fuel pressure but the fuel injectors must open to put gas into the engine.

A noid tester or plain testing light will show if the injectors are opening. A spray of starting fluid will also indicate if the engine is not getting fuel despite fuel pressure. It will try to run with starting fluid if it has spark.

When you find out whether it runs, if not, then check for spark if the starting fluid does not make a difference.

It is questionable whether new spark plugs were needed if installing them had no effect. Check other service places.
