I have a 99 Aurora. When you start it it runs rough. Chugs at idle. If I stop on the gas it makes a weird noise pops a few times and it'll go but cutting out as it gains rpm but will smooth out if I let off gas

My guess.....Spark plugs. BTW, is the check engine light on?

Service end soon is on. Just surges bad when you stomp on it and when it's cold

What does the check engine light say when you pull the code?
Last random misfire code I had was fixed by plugs and wires. Plugs looked decent, wires didn't test bad either so I was chasing my tail for a bit.
But pull the codes and see. Sometimes a coil pack or something goes bad.

But pull the codes and see. That's the only way to find out what the trouble is. |

Sounds like a bad misfire. Plugs, wires, coils, fuel, could be anything. As the others said - need to pull codes.

95 with 65,000miles on it. Given to me. It sat unstarted for 2-3yrs. I replaced the fuel pump and filter. Drained the gas tank. New battery, new spark plugs. Got it started and drove around the block. Not much response when stomping on the pedal. It stalled on me at a stop sign. After 30 minutes it started again. Fuel pressure was low. New FPR,no help. Took it to a dealer. Intake/gasket leaking. They put a used one on. Then said the computer needs replaced. They also put a new radiator on. Told me "now your water pump is leaking "
After 6 months of being pissed about the money I've wasted, I took it to another dealer to have a new water pump put on, as a ONE MORE LAST ATTEMPT. They just called and said "it's ready. Do you know it's running rough and the check engine light is on?"....
