So i set the timing, replaced pick up coil, replaced spark plugs, ignition module, cap, rotor. Runs good But i still have the pulsating idle, runs good just annoying at idle. Im beggining to think its my injectors....when i replaced the einjectors a while back i put in injectors from a 98 3.8 mustang , four were the f1ze and the other two were a diffirent model number.. the f1z3 had four little holes were fuel shoots out. the other two had four way bigger holes were fuel comes out. Do you guys think that could be causing an uneven idle or something?? btw i have a 92 camaro rs 3.1 what injectors do you guys recomend for a 3.1?

 

Look up Southbay Injectors on here. Great guys, awesome product.

 

While getting proper injectors is a great idea, make sure you check some other factors as well. Check your vacuum hoses for leaks. Check your FPR for a ruptured diaphragm. Check your fuel pressure and ohm your injectors. I got my injectors from Southbay and I was very pleased with the injectors performance. Good luck.
