1967 Chevrolet Corvette cold start problem


Yes your ignition timing could cause your car to start hard when it's cold but I think that you should check the choke setting on your carburetor. And since it's a older car i was just thinking that I doubt that you have upgraded to a HEI ignition and you are still running a breaker point distributor and your points could be worn or needs regapped. Either way i know that most people forget to set the dwell on points too which will cause the same problem the best way to set the dwell is with a oscilos

Gas not staying in carb, when cold very hard to start


it sounds like the choke isn't closing on the carburetor when the engine is cold ( more gas, less air). normally step on gas pedal once to close choke before starting. need to find someone familiar with carburetors to help as it can be technical setting it up

My 1969 GTO takes forever to start in cold weather, once it catches and warms up it runs fine


Assuming the engine is in good shape and not in need of a major tune-up, check your carburetor choke. It's not closing when cold. Clean and adjust.

Get a service manual and follow the instructions. Far too complicated to cover here.

Also, make sure you know how to properly SET the choke on a cold start. Slowly push the gas pedal to the floor and let up. Start engine without touching gas. If it's REALLY cold, like 0 degrees, you can hold the pedal halfway down while starting, after setting the choke.

Carbeurator problems


Cold starting problems from a carbureted engine? Bet if you get your choke adjusted right, it will solve it. If you can screech the tires, this Tercel may be worth saving!
Just get a mechanic friend or pay someone to fix the choke. Doesn't take a long time if you know how. If you've never adjusted or worked on one, it's not so fun. Hard to explain too. The choke plate or flap should be almost closed completely when starting. Soon as engine is cranked or running, the plate should open a small amount more, but still nearly closed. Then as engine warms, the plate should gradually open until it is completely open after about 5-10 minutes. The choke cuts off the air supply to the engine. A cold engine needs a richer gas mixture to run good, and most importantly to start easy.

1986 toyota truck electric choke


Is it hard to start? The choke has some notches on the side by the electric choke plug...rich to lean...If hard to start cold, loosen choke screws on side and turn the dial toward close (rich) retighten adjustment screws and recheck performance...If choke stays on to long after warm up (idles fast) adjust the choke toward open or lean position. Try no more than 2 notches either way between tests...Hope this helps.

Hard starting, rough idle when cold, then smooth running when warm


Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.

When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.

When car warms up it misses and dies and is hard to start what do you think is wrong


I am going to guess at the easiest first .
I will attempt to explain my reasoning without going into it so far as to bore anyone...

Coolent tempreture sensor ;
When the car is cold it starts fine , as it warms up (coolent temp sensor) the ECM is signaled to decrese the rich fuel mixture (choke).

Test coolent sensor for variences in reading with an ohm meter to verify the sensors condition.


Plugged fuel filter;
Cold start , fuel is sedentary allowing particles to settle (paired with the enrichened fuel mixture of cold start), Then when warmed the particles are clogging the filter and the fuel enrichment of the cold start is no longer helping the starving condition...

Its hard to diagnose with what little information you have provided.
If you are ghetting a code , take it to the nearest AutoZone and get a free diagnostic done.

Stalls when engne warms up


Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.
