does anyone know of someone who specializes in lt1s around delaware, pa "philly area", or south jersey.. Have been having a problem running really rich bogging in between 1500-2000rpms. Also, when i did the plugs rear 2 plugs driver side were carbon caked. replaced air filter, cleaned tb, replaced coil *had lots of corrosion* tps sensor, map sensor, and egr valve. any ideas or someone i should go see?

 

I take mine to a local shop in folcroft, right by the airport. They've done great work on my car for the past 6 years. Also, the owners/ head mechanics son has a 95 z28 that also has a lot of work done, so they are familiar with the cars. Very quick turnaround as well.
