I have a '93 Volvo 850GLT, and recently it’s started acting up on me. It starts fine, but once we get rolling it feels like when I press the gas pedal, the engine doesn’t get any gas. If I try and idle it, the engine RPMs die down and the engine dies, but if I press too much on the gas it refuses to accelerate unless I coax it. I can keep it in first gear with just the right amount of constant pressure on the gas, and I found that even though when I press down on the gas pedal to accelerate nothing happens, when I release the pedal, as it returns to its regular position the engine gets a kick. If I rhythmically work the pedal a little, I can get it to accelerate and eventually shift up. If I apply too much pressure, though, like I said, she stalls and that’s that.
Because it doesn’t want to shift, my mechanic says it’s probably a transmission issue, but my car is an automatic and A: I don’t wanna spend that kinda money on a transmission right now and B: A few of my more car-minded family members say that when an automatic transmission dies, there’s normally muck or metal in the transmission fluid, and my fluid is fine. Could it be something to do with the fuel pump or gas lines?
