Going down the highway at 55-60 mph I just barely tap the gas and the vehicle jumps, I press the gas hard and it stops, leave off the gas check engine light blinks and jumping continues.


A blinking light usually means exhaust system probably catalic converter. You most likely have a small blockage in it which means exhaust can't get out correctly. Have vehicle scanned at autozone or similar.

Drive cycle reset


Drive Cycle resets to reset the OBDII testing phases are very specialized to the year, model and engine of your car. So I can only speak generally. Start the car from fully cold and let it idle for about 15 minutes, then put the car into gear and drive it for about 5 minutes at 35 mph, then get on a highway and drive at about 60 mph for 15 minutes, come off the highway and drive around 40 mph for 3 minutes, come to a complete stop (like a stop sign) wait 30 seconds, drive off again up to 40 mph for 4 minutes - and repeat the last 2 steps (going up to 40 mph) about 3-5 times. Then repeat the last two steps going up to only 25 mph. Then come to a complete stop in your driveway and let the car idle for 10 minutes with the a/c on . After this is done, hook up a code scanner and see if it reset the modes to "ready".

How to improve 2011 hundai mileage


Driving habits are the main reason for bad mileage including: excessive idling, fast starts and stops, fast driving in general...best speeds are 50 to 60 MPH for economy, city driving uses most gas,
Mechanical problems include underinflated tires, leaving windows open at highway speeds, not keeping engine tuned up, not changing lubricants at proper intervals, not greasing wheel bearings, not aligning and balancing tires..etc
