87 T-Type stopped running

[ATS666]

Heres what has happened.

1987 T-type (intercooled) [09/86]
Rebuilt motor, new spark plugs and wires. The car ran great (only taken in and out of the shop and on a test drive) and then it stopped running well, actually barely runs. takes alot of cranking and have to hold the rpms up to keep it running.

No codes or anything

What should I check on it first.

Thanx alot guys!!!

Try disconnecting the MAF sensor and see if it runs any better.
