I have a 89 thunderbird and it has been running bad for a few months now.
If i drive over 2000rpm's it runs fine but when it is under 2000rpm's it runs
horrible.It doesn't try to stall but lacks power and shakes some.
I had a complete tune up done.I also replaced the fuel pump and filter.
Both oxygen sensors and both catalytic converters.With only a 6cyl i am only getting 10mpg.Brought it to a shop they replaced sparkplugs for a second time now and put fuel injection cleaner in saying an injector is sticking.
Went through that fuel tank and still running bad.
