Wont go from stop/small inclines jerks also when accelerating

When the engine really got hot is there a possibility you may have over expanded some parts and now the engine is sort of tight and is not spinning fast enough to start.

Check for spark and fuel delivery but ......................

see repair shop or dealer

sounds like to me the fuel pump is not getting the adceute fuel pressure to supply the demand of acceleration check fuel filter

ENGINE HESITATES WHILE ACCELERATION

LOSS OF ACCELERATION

It can be fuel pressure issue or it's the problem with accelerator pedal or its clogged filters causing there.

There are many other possibilities. I suggest you to go through the list of help links mentioned below, these will help you to confirm where the actual fault lies: -------

Check fuel pressure. If good, rebuild carb.

MOST TIME CAR STUMBLE OR HESITATION ON ACCELERATION YOU.HAVE A SLIGHT LEAN FUEL MIXTURE.CAUSED BY STOPPED UP FUEL INJECTORS OR FUEL FILTER SLIGHTLY PLUGGED.

When you accelerate, it open more throttle valve and at the same time more fuel is supposed to spray in to meet the demand, but it didn't that why the engine is hesitate. The problem is that you don't have a correct air: gas ratio of 14.6 :1 Need to check 1- Fuel pomp rate of delivery to determine pump is weak for a change. 2- Fuel accumulator ( regulator) if it still maintains correct pressure for Fuel distributor 3- After the#1 2nd #2 fixed and the problem is still existed, then your Fuel distributor need to be taken care of.

this could be an air intake problem, check the air filter but what ive seen before is the flexible intake pipe collopse only when the engine was under pressure as you describe.Try removing this pipe & driving again but not for long as dust would enter the engine .it might confirm or elimiate this.

I would have the catylic convertor checked.
Then have the transmission check . I am guessing the transmission is automatic. The torque convertor could be shuttering when slowing down to a stop.

try cleaning the inside of the MAF sensor and do the following procedure as well.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
