carb or FI?

Shake and miss-fire.....have you noticed any other symptoms? I would check spak plugs and hight tension leads for cross/miss fire firstly as this would be the most common cause. Once you are confident that these are not the problem you then have to open the can of worms. Most vehicles produced after 1990 are computer controled. This relies on sensors sending sending information to the computer so that it can deliver the correct spark or fuel mixture at the right time. If a sensor is sending the wrong info the computer sends a faulty adjustment which will cause a miss fire which will cause your vehicle to shake and lose power. The quickest way is to plug an analizer in to check the sensors. If that is not possible for you then more info is needed to give an educated guess at a correct diagnosis

noif WOT vacuum is near (not at) atmospheric pressure then theCab is not undersized.you do know oversized carbs can never be tuned , right?the carb can only deliver more fuel mix, and make more powerif the engine can breath more air.so we do vacuum tests to see if a bigger carb can help.on most cars , no. 1.4L is a small engine. and can be very easily over carb'dI use a baro gage, (Sensor) and key on not started, is my Atmospheric pressure, it will be 0 pressure. (absolute)14.7 psi 0 abs pressure, at sea level.i start the engine and see idle pressure. (near max)i wide open throttle the engine, up a hill and see if it drops near 0but not zero, the carb will stall near zero.the venturi fails there. hard.to learn this , read the full spec. on your carbs. see the specfor minimum pressure drop to to bottom.there must be X drop or the carb stalls. The carb fuel nozzles, die of near this point and can not be tuned.one great exception to this is CV or SU carb, they adjust automatically to this pressure.Think of this one other way.The engine pumps air (end to end, carb removed.what is that CMF,(cubic feet per minute) buy a carb to match that.bingo.there are great free computer models to do that.

Remove the rear seat and there is a place to adjust the spring rate.
