Alright so my dad bought this 1988 thunderbird turbo coupe brand new and has had it ever since. It sat in storage most of its life as far as i have been old enough to remember only to be brought out ever few summers it has like 75,000 km on it. Anyways the first time i drove it i stepped on it and it seems to build a bunch of boost and just sputter and had no power.
The timing belt broke on it shortly after that. I replaced the timing belt and it worked the same. My dad took it to a friend who is a mechanic shortly after this and he replaced a cracked exhaust manifold and tryed to determine the problem im not 100% sure what all he did but after sitting there for a long time he determined it was the mass air flow sensor. We brought it back home and bought a new maf sensor.
It doesn't build alot of boost and sputter like before but it has no power at all and idles very high sometimes then drops down and quits it is also hard to start sometimes.
I did the koer and got codes 25, 34, 41, 76 i looked them up and the only two that meant anything to me was system too lean and something about the egr. Can anyone point me in the right direction on where to start. I'm thinking plugged cat? bad fuel pump? I'm going to pick up a fuel pressure gauge tomorrow to check the fuel pump then go from there.
Sorry for the long post and thanks in advance for your help. My dad says this thing is fast but im not impressed yet from what i've seen so far my sir civic will walk all over this thing :giggle:
