Hard to start when the engine is hot

start off by checking the transmission fluid when its hot and in park for the proper level,
check the color of the fluid compared to new fluid,
volvos probably use dealer specific transmission fluids and there is a possibility normal shelf trans fluid was used and that can cause all sorts of transmission problems.
hard shifts can also be related to transmission and or engine mounts. visually inspect those for wear and or breakage.
dark fluid or particles of metals on the dipstick can be a sign of major transmission problems
clean the dipstick off with a clean white rag to check that.
if its low make sure to use what the dealer recommends even if its high dollar, but if the fluid is already burnt smelling and or contains metal materials it getting time for a rebuild or replacement,
. at that price the previous owner might of known the transmission was going south.
good luck and hope you get more miles out of it.

Your vehicle uses the coolant temp sensor and the intake air temp sensor to determine the engines temperature on a cold start. If one of them is dramatically different than the other it will flag a code.

Is the check engine light on?

When was the last time you had a tune-up? if recently what brand of plugs where used?

Have you noticed any hard start issues after a hot soak? A hot soak would be driving the car until fully warmed up, shutting of the engine for approximately 15 to 20 minutes, and then starting the engine again.

can I use 3C T engine for my Corolla CE 110 diesrel car with out any change?

When going up hills is the engine bucking and missing? Also for the hard start warm problem, check the fuel pressure regulator for leaks into the vac line.

ya it can turn off by itself ,its will be hard to start the engine ,because the head has gone so its burn,this will make the compression in the cylinder chamber leaks,so its hard to start it

multiple corrections.. possible thermostat,fan, coolant. waterpump etc

I am trying to understand your problem. Check engine mounts. Have a driver in the car, hood open. Start car, foot on brakes, shift from park to reverse and back again. Shift through all gears, look for unusual engine movements around engine mounts area. Left foot on brakes, press gas in drive and reverse;watch for excessive engine movements. Be careful as you perform these steps. You may also want to check drive axles. Keep me updated.

does it have a cold start injector seperate from the other injectors usually on the upper intake somewhere with a fuel line going to it

U MAY HAVE A DEFECTIVE ENGINE COOLANT TEMP (ECT) SENSOR, U NEED A SCAN TOOL TO TEST THIS PART, THIS IS NOT THE SENDER FOR THE TEMP GUAGE THIS IS THE SENSOR THAT TELLS THE FUEL INJECTION COMPUTER HOW COLD OR HOT THE ENGINE IS, IF IT READS LOW THE SYSTEM WILL GET TO MUCH FUEL AND CAUSE A HARD START, DO U NOTICE ANY BLACK SMOKE WHEN IT FINALLY STARTS?

Hi. 2005 Corolla CE. It's normal. They tend to do this when upshifting form 1st to 2nd gear. No timing chain readjustment needed.

96 Corolla. Overdrive not working properly, if not engaging after 45mph constantly. If driving on the city, is normal, but not after 45mph, when the car is trying to engage overdrive in order to save gas and preserve the trans gears. If not able to get help at the dealership, find another one and explain them the situation.
