The car vibrates under your feet at about 50 miles. The abs and check engine light stays on. What signs that it could be the throttle as well as the abs.

If your car is vibrateing it could be your wheel balance or engine mounts might be cracked or broken. As for check engine light check all water and oil levels and make sure they are were they should be, if fuel injected you may also have a blocked injector and it isn't getting the fuel it needs but the car will sound off if this is the case or it maybe getting to much fuel easy to tell via fuel mileage you are getting. Your abs light might be staying on because your wheel balance is so far out it has shaken the sensor loose and it may also have destroyed the abs sensor or lines (you have a small plastic hose that goes from wheel to sensor look to see if this is broken or fell off or cracked). If none off the above email me at [email protected] leave me a message and I will try to help you further with a few more things you can check. The most important one though is the check engine one it may just be a fuse but it maybe that there is something in the motor as in sensors and timing that it may be. Oh and when you hit your brakes really hard does the abs work or not?
