Hello I have a 1993 LX 5.0, bone stock, after I took it out of storage this year, it is acting up really bad. I accelerate and I have no power and it back fires often. It is EFI. Sometimes it will run really well and most times it is starved of power, this last time I was in 4th and I could not even get the car over 45 mph. Does anyone have any tips on what it might be?

Thank you!

 

bad gas, fuel pump going bad, clogged injectors... Something to do with the fuel system for sure.

 

if you didnt take any preventative measures against mice, your exhaust could be loaded up with dead critters.
