This is my first post here, have been waiting anxiously for 2 days to be able to post
I just bought a 1997 Thunderbird LX v6, and probably a money pit and headache generator along with it...
The engine..... oh the engine...
The engine runs rough at idle. The MAS is unplugged. With it plugged in the idle smooths out great, but the vehicle will then have no power and will not accellerate. I had a Toyota that had a similar problem and it was the TPS at fault. I also noticed that 2 O2 sensors had been removed (holes plugged and wires cut).
Does anyone have the procedure to check the MAS with a voltmeter?
Next issue... Oil pressure.... not so much.
This engine has oil pressure issues. I know the gauge is really a fancy idiot light, however from experience I know this engine does have oil pressure issues as I can hear the valve train making noises, especially when the gauge drops.
My first inclination is to pull the pan off the engine while its somewhat in the car, toss new bearings in there and put in a new oil pump. I know this is just a band aid but if it buys me 6 months, thats fine.
Option #2 is go to a local yard and buy a used engine and hope its ok. I don't know what year engines/components interchange with my 97 though. (v8 swap NOT an option at this point)
Option #3 is I just pull the engine completely out and overhaul it myself. Don't particularly like this as it entails sending stuff out to machine shops (and I am fairly new to the area and have no connections/recommendations on where to go for good work), also this option would take way too much time.
I can't drive the car right now either. After a short cruise around the block, one of the rear metal brake lines decided to rupture and shot brake fluid all over the ground, and of course the car now has almost no stopping abilities at all. I'll be addressing this as soon as my double flare line tool gets here in the mail.
After I get the brakes fixed, many more posts to come I'm sure.
