    Carb I belive has been rebuilt. Just got the car though, and I have sprayed starting fluid around and didnt have any response from that. New spark plugs, wires, cap, coil, rotor, ign module or what ever is under rotor.

    New fuel filter also.

    The choke should be closed when you start the engine cold, then slowly open up. That makes the mixture rich while the engine is warming up. If that is happening, and the engine runs rough, either the mixture is too rich, or too lean, or you have ignition problems. The mixture can be off due to lack of fuel coming out the carb jets, or too much air entering from a vac leak.

    Things like the EGR valve should not open until the engine warms up can also affect the performance.

SOURCE: My 1998 Olds 88 has been stalling and running rough.

Check and clean the IAC valve. Idle Control Valve. Use brake cleaner or carburater cleaner . Remove the duct work from the air filter assembly. It is located just inside . Run the engine at 1200 rpms and spray the valve. The valve can also be removed and cleaned.

SOURCE: 2000 dondge durango Code 201 and 455

A code p0455 most likely means one or more of the following has happened:
-A loose or improperly affixed gas cap
-A non-conforming gas cap (i.e. not factory/original brand)
-Other leak or damaged piece in EVAP system

With a p0455, the most common repair is to:
-Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
-Otherwise, replace the gas cap, and/or
-Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

As for P0201, the causes could be any of the following:
-Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
-Open in the wiring to the injector
-Short in the wiring to the injector
-Bad PCM

Possible Solutions:

  1. First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
  2. Check for voltage at the fuel injector connector. It should have 10 volts or more.
  3. Visually check the connector for damage or broken wires.
  4. Visually check the injector for damage.
  5. If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
  6. At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
  7. Replace the injector

Check the prrimary and secondary resistance on your coil. Also check the resistance of the plug wires and plug gap.

I've a 1981 Vette that idles very rough with a cold engine start.


You need to have the choke adjusted so it runs on a fast idle so the engine can warm up or you may need the carb to be rebuild and adjusted properly.

Ford 1981 f 150 not running changed Coil distributor cap Roar arm plug wires did not help started bur ran extremely rough then died


motors need 3 things to run properly. gas spark and compression. the starting point. also spark timing.
the motor you are dealing with is easy. i just rebult a 1978. anyways sounds like a timing problem . first i would check the distributer. if all is ok spay a squirt of starting fluid in the air filter, or even wd40.,,,,,,,see if it is gasoline problem. isolate where the problem is.

91 olds cutlass supreme runs rough and wont stay idle.


If your vehicle is fuel injected I would say you have a blown fuel regulator. This would cause excess fuel into the cylinders (flooding) causing a miss and coughing and also blow fuel into the air breather. If will also cause the vehicle to run poorly and could cause the vehicle to stall. Also to much fuel on startup can flood the cylinders and cause the vehicle to no start.
