I havent posted much on here, mostly due to forgetting passwords and whatnot. Anyway, I have a 91 Mercury Grand Marquis, love the car, but its got a few problems. The biggest right now is a surging problem.
While the car is sitting idling, you can hear it. Its not extreme, but definitely noticeable. Also when the car is cold in the mornings, I'll be going down the highway going 55-60 and if i stay consistent on the throttle the car starts bucking like a crazy horse. If I press the gas, even slightly, it'll stop, or if i let off the gas, it stops. This only happens for the first 3-5 miles, and thats it. I dont know if the two issues are related or not, i'm just hoping somebody can help me out. If it helps the car has roughly 165k miles (the odometer is broke but i found a receipt from late last year from the previous owner of an oil change and it said 145k miles), I am the 3rd owner. I changed the throttle position sensor a couple months ago, but it was a cheap one off ebay.
Any help would be appreciated
