I been having problems with my camry 1998.

1. When it idles, it goes off atleast 3 in 5 events
2. Whenni go on long journey, it jerks and and hard to accelerate smoothly
3. For 16Litres, (4gals) i hardly get 50Miles
4. When weather is hot it refuses to start until i wait for it to cool...but it cranks!

HELP

What engine does it have?

Check engine light?

With that many issues you'd be best to have it scanned by a professional. 1998 is OBDII so you'd have access to engine sensors where a graphing scanner would give clues to system performance problems.

Could be the ECT sensor. Engine Coolant Temperature. The ECU monitors this and adjusts fueling accordingly; richer when cold, leaner when warmed up. There are two ways.

Use an OBD2 monitor to read coolant temperature. This is the best way, as this is exactly what the ECU reads. When warmed up, it should be about 190 degrees F (88 C).

Use a multimeter to check the sensor’s resistance with the engine hot and cold. It should be about 3,000 ohms cold, and 300 when warmed up. The location of the sensor depends on which engine you have, V6 or I4.

Its a 4cylinder, so i went to a mechanic today and he said that theres a part on th fuel pump compartment that doesn't filter the easy its supposed to, so he removed it and washed it and return it back, i drove a few miles(about 25) in the hot summer sun but it didn't jerk.

and Update:

The rough idling is from the choke he said, but the car starts with no long cranking tho

This engine doesn’t have a choke. That was something that carburetors had. This engine is fuel injected, so there is no choke.

Perhaps you mean the throttle body? They get dirty and need cleaning. There is also something called an IACV, Idle Air Control Valve mounted on the throttle body that is responsible for maintaining idle RPM. It gets dirty also, and needs to be cleaned. It’s best to remove them both for a thorough cleaning. It’s impossible to give them a good cleaning without removing them.

Usually if it doesn’t want to start when warm usually it’s a fuel pump issue or something with the fuel system

That’s why I recommended checking the ECT. If it is an open circuit (infinite resistance), the ECU will think the engine is always cold as ice, and run the fueling very rich all the time.

In the future, you can do some basic checks yourself. Air filter is important. If that is blocked by things like dust, you can get bad economy. You can open it easily and clean, it's the black box near the battery. After that, you can slowly learn and clean each part.
