My Nissan Exalta 2000 STA jolts when it engages gear, it also consumes a lot of fuel which i believe is way too high as expected from automatic car.

STOP...This is one to leave for a professional you're dealing with fuel gas itself actually is fairly stable it's the fumes that burn rapidly and explosion... simple static spark can ignite from polyester or nylon clothing. Just leave it to a pro Safety first ....If you're going to do it anyway. JUST DON'T ATTEMPT. ****EVEN IF YOU HAVE AN EMPTY TANK IT'S ACTUALLY MORE FLAMMABLE **** STOP DO NOT ATTEMPT PERIOD

I can't exactly answer your question.

Most cars have a fuel filter fitted in the fuel line and it is this that needs routine replacement. Most such cars are also fitted with a prefilter gauze at the fuel pump intake requiring no maintenance under normal conditions.

A few vehicles have no in-line fuel filter but instead are fitted with an in-tank lifetime filter, again requiring no maintenance in normal conditions.

If you are experiencing trouble I believe the only way to access both the prefilter and lifetime filter is by removing the fuel pump/gauge unit assembly.

Engine temeprature sensor may not be working properly, tricking the engine computer to believe the engine is always "cold." Ome engine comuters may not detect a failed engine temp sensor. Another possibility, and more likely, is a defective fuel pressure regulator. It may force the fuel pressure to be high, which results in more fuel being injected than the engine expects or needs. Check the fuel pressure int he fuel rail.

Has the car been running on empty recently? Running with low fuel can damage your fuel pump because on some cars the gasoline is the lube for the pump. a bad fuel pump could be the problem. Look up some YouTube videos on how to diagnose

check tranny fluid

hello there, had to do some looking up as to what NISSAN EXALTA 2000 actualy is. i reside in USA and we do not have exalta on our streets. here, its a powertrain aka engine and transmission in a NISSAN SENTRA so it should be very similar to our sentra as far as setups except for different body. I think that you have an issue with the CRANK ANGLE SENSOR. i would start with replacing the sensor. is the SERVICE ENGINE SOON light on??? if so, that could be for many reasons and one of them would be crank angle sensor issue. nissan had problem with those sensors. they would cause the car to die. nissan had campaign / free replacement program in those model years of nissan sentra 2000 year model. have the crank sensor replaced. start there. like i said very common problem.

check the level of the power steering fluid.

i would start by checking the mass air flow sensor or put a scan tool and checking live data.long trim and short trim fuel. may need a dealerfor that.

you might want to check the brake pads. it might be thin enough to make the wear indicator touch the rotor disc.

Hi there. Although the Dealer has changed the oil, did they do a 'Stall Test' whilst the gearbox was cold and again when at normal running temperture? If not, that's what they must do firstly. This will identify whether you have a slipping clutch/s. The Honda autobox also includes what is known as accumulators - these control how each clutch is engaged during acceleration. For example, if you are accelerating slighly/smoothly, you want each gear to be engaged gently and smoothly, whereas, when accelerating hard, you need the gear engaged quickly and hard to aviod clutch slippage. Thus, the fact that you are experiencing a hard engagement might mean that an accumulator/s is seized. If that's the case, it will mean that the autobox will need stripping, cleaning and be checked for worn components. Hope this helps, Scottech.
