I have a 91 Z28 with 350 tpi, and it ran fine before I put new injectors in it except for a bad jumpy idle. I replaced the injectors with Bosch III 22lb. Now it idles perfectly. The only problem is that when I first start it up and put it in drive and push on the gas it feels like it wants to die. After I put start going it only wants to die for about the first 30 seconds. Then after about 30 seconds it runs perfectly, no problems at all, and acts like it should. I find it odd that it only messes up in gear and the first several times I push on the gas. Any help would be appreciated.

 

anybody have any ideas what it could be? I find it odd that it only does it the first few times I push on the gas and after I put new injectors in it. They are not leaking either.
