Well today I installed a set of 30# SVO injectors, and put new brake pads and rear rotors on the car. I had my previous pcmforless program, brian gave me a new one, with some fueling upgrades. I then put it in tunercat and bumped the rev limiter up, and changed the injector constant to 31 (to compensate for the additional pressure the LT1s have)

After I uploaded that I installed the brakes, and took it for a drive. Drove around the neighborhood a bit to get it warmed up, get some oil moving, then took it on a wot run. While I was slowing down, the car was idling at 2k rpm. So I came to a stop and the damn rpms wouldnt drop. Normally it would idle about 1500, and then when you came to a stop it would idle down back to ~1k.

So I shut it off and restarted it, and it jumped right back to 2k. Came down to 1.5k but no lower.

Any ideas? I have the datamaster file if needed. For some reason I was geting data errors ALL the time, and the PCM was throwing a ****LOAD of random codes.

 

Actually I dunno if the datamaster file will be of any help, its all screwed up.

 

I also have a small thud (thud isnt really the right word of it, maybe pop) when I push the clutch in.

 

Did you also clean the TB? I found that when I cleaned my TB my RPMs would hang. Dab a little oil on a QTip and rub it into the TB blade shaft (where it enters the body).

 

Car fixed itsself!

I pulled the pcm fuse, and came out later on and tried it, hopped to 1500 rpm and dropped to ~1k

All is well now, perhaps I can get a real datamaster file tomorrow.


My ebrake used to be loose after i did the brakes, now it autotightened itsself as well!

 

Ha, I was just getting ready to tell you to do that, lol. Hopefully your problem is fixed. A lot of people seem to be having high idle problems on decelration from pcmforless.....
