The car is an 87 daytona shelby z. Car sat fine outside for 8 months and fired up soon as i tossed a battery in. Moved it into the garage for a week to get computer/injectors changed back to stock. Now the stupid car will run for 20 seconds then idle drops to almost zero and pops and sputters until it finally dies. If I keep my foot on the gas it will stay running but get the check engine light to flash and idle has a mind of its own. When it starts to act funny the asd relay in the power module clicks like crazy.
Running good had +40 injectors/ fwd ecu/ 3 bar
Poor running and dies stock injectors/ stock map/ and stock ecu.
Changed out hep, pm, lm, coil, map from a good running car 10 feet away and still get the same issue.
No codes
UPDATE,
car now runs at 2200-2500 rpm constantly, as soon as it gets warm to drop idle the car cuts out and dies. All power drops out, the dome light even goes out when the car dies. Unplugged ais no change, unplugged map sensor no change.
