Sound like you either have a universal joint on the way out or a balance issue with the driveshaft. The vibration at idle might be an engine miss or its running lean. With that many miles it could be a simple vacuum leak at the manifold, but that should throw a check engine light. Maybe check compression on each cylinder to make sure they are close to equal. It could be just a worn out engine.

Vehicle: 03 Chev Astro Cargo Van. Style: 2WD/RWD; 4.3 liter Engine Problem: Yesterday, 'Service Engine Soon' light came on, today Brake light and ABS Light came on

It could be many different of things, but I would check the charging system and battery first. I have had many under charging GM vehicles that all the dash warning lights would light up.

Reset tire pressure sensor

My work van is a e-series 2011 cargo / work van, the way to reset the tire pressure on it is too push the hazard lights button a few times, may 5 or 6 times pretty quickly when the van is in park and running, the horn will honk and and then you stop pushing the hazard button and wait for a few minutes and the horn will honk agian and the tire pressure light will go out, i dont know if this resets the tires pressure sensor, but the light on the dash goes out, on my van it comes back on after i restart the van , so I am guessing that the sensor on my van is bad. but its worth a shot on your car.

I have a 2003 gmc safari cargo van, and the problem started when it got hot outside, it started overheating and lost power, i replaced the thermostat, coolant, spark plugs, and MAF sensor, the overheating...

Hello and welcome to FixYa!

I strongly suggest that you replace the transmission fluid. If the fluid is burnt the transmission tends to be sluggish and finds it hard to shift gears. This will surely give great stress to the engine. Once the fluid is replaced, smooth drive and shifting will be noticeable.

Hope this helps and thank you for using FixYa! Have a good one!

My 2003 gmc safari cargo van has been trying to overheat when I turn ac on what could it be?

If your gmc safari cargo van overheats when the ac is on, your radiator and cooling system may be clogged and not working at peak efficiency.

Make sure your radiator cooling fan goes on as soon as you turn the a/c on.
