Yes, it most likely will be a costly proposition if you take it to the dealer. It's difficult to diagnose a problem with most vehicles in this situation due to the many possibilities. The FIRST thing you could do is to find out what the engine control unit (ECU or Engine computer) is detecting as a problem. This is usually a free service that is performed by local auto parts companies like Autozone etc. Try that first to see what component is failing then you can move on from there.

Check your transmission fluid. Usually if your rig starts shifting hard ( big Jerking motion) it's a sign that your transmission is terminal and the ring is going between the gears

I got a chevrolet spark. When cold she runs perfectly, but when warm she jerks the whole time. What could it be? Please help me

If it has been regularly serviced and tuned up It sounds that it could be a TPS...( Throttle Position Sensor )...or perhaps an 02 sensor...Oxygen sensor...Idle Air Control valve will keep the idle up until vehicle gets warm then it brings the idle down..there are a few things that could cause this....However If any of these are at fault they should flash a trouble code...I have seen times when no code flashed ...Your type vehicle is special....I would check for recalls......In fact don't waste time trying to repair it without trouble codes...Take it to a dealer.

You have to find the reason the check engine light is on. This will aid in diagnostics. Also, are you buying fuel at the same place both times?

Why is it that over revving results in more black smokes? Is it a good standard for smoke test to over rev? I own a 1 year and 5 months Mitsubishi Montero Sport with 13,000 kilometer mileage. Also, a Mazda...

The Effects of Over Revving a motor can be Catastrophic. I do not understand why the government would require someone to do such a test. Normal Emissions Testing is done at High (2100 - 2500) and the Idle (500-900).

Reason for Increased Smoke.... As you increase the internal pressure of the vehicle, you are creating a VACUUM and this is suckking the Oil past the rings, and anywhere else that it is causing the Vacuum.

Efffects of Over Revving van be Premature Failure of the engine (Could cost you $5-$8,000 to replace)... I would ask WHY so high... A Diesel would MAX OUT their RPM @ 4,000.

These people who are doing the test, ask them to show you where it says in WRITING 4,000... That is much higher than in the 4 states I have been certified to be an I/M Inspector

You should have this problem scanned as soon as possible. Usually when the engine light comes on, it means you have a problem But if it blinks its a warning that u should pull over and shut it off to prevent damage to your engine & its parts. It sounds like a fuel injection/emissions problem. I ignored this problem once & it melted my catalytic converters!
