Default wont run when warm

My friend has a 89 with very low miles..His mechanic has it for months now changing everything he can .if it don't work he puts the old part back and stsrts over.. the problem is the car starts fine then when you try to give it gas it bogs down like a choke problem..New gas .new conputer, new sock and fuel pump..I have a c3 and give him much help with the high tech stuff.

Have the injectors been replaced ?? The 89 injectors are problematic and have a high failure rate. Have him ohm the injector coils, cold and then hot.
Check out FIC's injector sticky at the top of the page.

You may want to check your FPR diaphram too.....do a pressure check and watch the bleed down times.
