Sluggish Acceleration

A high mileage vehicle usually suffers from any number of maintenance related deficiencies. I would address the Fuel filter maintenance first. It's the cheapest and easiest of the solutions. Lack of fuel pressure under higher demand due to acceleration will result in a sluggish engine. The engine would idle fine and even run fine at high speed but would be sluggish under acceleration. Other more complecated solutions would be worn Ignition coils, Worn spark plugs, Timing belt stretched or jumped timing and the most expensive would be loss of compression in the cyllinders.

Why does the engine become sluggish when A/C is running?

The air conditioner runs off of the motor and takes a good deal of power away from it. I ALWAYS shut my air off when preparing to pass a vehicle or getting on an on ramp.Unless you have a diesel or a V 8 the air conditioner will affect your performance of the motor greatly.

My 2005 Santa Fe check engine light is on. my car does start but when is is started the check engine light is still on and well not go off. could it be the fuel filter cause my engine does jolt like if it...

Engine check lights should not be ignored and should be checked by a mechanic or dealer via a diagnostic tool as soon as possible. It may be a simple glitch but, it can also be logging a serious code that needs immediate attention.
The reason it feels sluggish is because when your check light comes on it logs a code, older cars need a couple of codes to register before it causes the ECU to put the car in to limp mode. This means it won't drive as well as it should and will lack power, this is to protect the engine from possible damage.
Engine check lights and other check lights on vehicles performs the same function as pain in our bodies.
When we are in pain we see a doctor, OK we can take a pain killer but eventually if it is serious we will know about it.
If we went to the dr, sooner we might have negated anything more serious.
This is the same for your car.

I have a 2000 audi a4 1.8t and seems to run sluggish over a 100kms, no engine light on, any possible reasons why?

If it runs well but is low on power it is possible that you are not getting any turbo boost. The wastegate actuator may be bad. The n75 valve that controls the actuator could be bad, also the N710 diverter vave may be bad.

Engine Service Lights

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you should have the car diagnosed and repaired. If you can tell me the code I can give you possible causes.

Engine light on Infiniti J30

Could be....I would first very simply check the gas cap. A loose or cracked gas cap could cause an O2 (oxygen) sensor to react and light up your "check engine" light. if the cap is indeed tight it may be an actual faulty sensor, in which case I would have your ODB plug under the steering wheel read by the infiniti dealer. Devoe infiniti is great here in Naples, FL!
Hope this helps,
