Re: Removing secondary throttle valves...Help please.
Interesting stuff up there
More than just LT5 Experts! Here's an update for anyone who cares. As I pulled the injector rails, I noticed that the secondary inj's have been replaced at some point with accels (at least they look exactly like the accels that I just bought). I took an ohm meter to each of them and was surprised at the results.. All of the 8 accels were identical resistance (to the tenths) at 14.6 ohms. The primary's look like they are original and the values ranged from 5.6 to 12.4. you may recall that my symptoms were the horrible missing upon acceleration and some missing at idle with the classic "rod knock" noise, which you've pointed out is hopefully the flywheel. Wouldn't the poor numbers on the primary injectors explain why the car runs horrible until it gets to about 4000 rpms (guessing at this number because my tach is broken) and then seems to smooth out and take off, though it's obviously not pulling like I know it should..comparing to my old lt4 with the hotcam. I'm tempted to reuse the accels and just replace the primary 8. But I think I will just go ahead and replace them since I already bough em. I tested the injectors cold obviously. The other surprise I got was that I found the starter to be new looking. The valley was gunked up pretty good but not as bad as I would have thought, judging from seeing pictures. I don't have the typical leak around the breather. I think I am going to at least do some clean up of the IH and plenum ports. Depending on how much information I find. I'm really not concerned about having to take the plenum off again if need be since it should be a piece of cake not having to drain anything and having removed the secondary throtle blades. So again, may take a chance at the secondary injectors being good since they ohm out okay. |

Re: Removing secondary throttle valves...Help please.
You should definately change the primary injectors.
Accel 150821 http://www.jegs.com/i/Accel/110/150821/10002/-1 These will work for primary you take off the lower o-ring and they seal around the body of the injector. Pete
