i have an 87 7 n/a with rebuilt engine. it has about 6000 miles on it, it has been sitting for a year and i just got home for the summer and decided to start her up it ran like hell. rough idle poor acceleration just really doesnt want to run. i changed the oil and the plugs but did nothing to performance i need some help!!

 

DEFINITELY TRY MARVEL MYSTERY OIL IN YOUR OIL AND YOUR GAS!!!!!!!!
I guarantee you, you will notice an immediate improvement.

 

And yes, check the TPS, the timing, and set your idle.
Download the factory service manual from www.fc3s.org and follow the instructions for setting the tps,timing, and idle.
