hi I am new here. I have a 90 corvette that the dealer told me needed about 2000.00 in work. I also have a 92 Bonne. My car would not run at all. I went to the corvette forum and posted my problem. Everyone came back with multec injector failure. I ohmed checked the injectors and sure enough I had 2 shorted ones. I contacted the c4 injector guru,
Jon at Fuel Injector Connection Fuel Injector Connection and bought a set of Bosch des 3 injectors for 169. for the whole set. I took a whole day and put them in . The car has NEVER run so good. I just finished putting the same injectors in the Bonne, I bought this car new and let me tell you. It has more power than ever.
Check out this thread. Its even a sticky over there Alot of our problems seem to be that these injectors are not e10 compliant and the alcohol is ruining them.
