Subject: Re: 1985 CORVETTE TPI RUNS ROUGH by bogus on 2010/6/12 23:30:12 I am betting those are stock. Are they painted black? If you can - and this is a pain in the tuckus, really - remove the injectors. Leave them on the rail, but remove the rail. This requires removing the majority of the TPI (sorry). Remove the rail, but leave it connected to the fuel lines. Next up, put a strip of cardboard under each bank. Then, turn the key on and look to see what happens. You should get an immediate spray of fuel. Turn off the key, and see which one is weaping. You can also test this, to a degree, with a fuel pressure gauge. I defer to FIC for specific injector needs. But if those are OEM, I would replace them. This could also be a failure of the 9th injector. It is designed to richen the mixture during cold starts. |
