microtech, help
i have a lt-8 on my 87 turbo II with a streetport, full rb exhaust and stock turbo, problem is that one night the car was running fine a little on the rich side but fine, but the other night it stated to act up it wouldn't go past 3200 rpms it would just backfire like crazy so i checked the maps and tuned the mixture down a bit but its still not going past 3200 rpms, I don't think its my injectors cause they were working fine, unless i got a really bad tank of gas, could it be my timeings to retarted? am in a rut right now its been a real hassle to drive it if any one has any ideas please help
Thanks Eric |
do you have a wide band??
if so what are the readings?? have you changed your plugs?? |
plugs are new and don't have a wideband, but the readings are anywhere from 11-15, if it helps
|
how do you know what the readings are if you dont have a wideband???
|
the readings from the hand programer, there from the narrow band, so there prob not accurate
|
You're right. Narrowband is really only accurate at stoich...
You're REALLY going to need a true WB if you're going to do any tuning/troubleshooting. IMO it's a good investment -- esp. for a boosted motor. |
They are cheap now too...300.00 makes it a done deal.
|
Check the connectors on both of your secondary injectors.Make sure both injectors are working fine & no pins have backed out of the plug or something stupid like that.
You will most likely have your RPM stage set at 3000 & there is a problem with one of the injectors/connections when it is switched on. For a quick test try moving the rpm stage value from 3000 to 4000 & see if the stumble moves up with it. |
i'll check the connections and move the stage up and let you know the result
as for the wideband i think my friend may have one so i'll call him up. |
I think i may have found he problem, i think its my tps.
I checked it and it wasn't calabrated so i did it and the car ran fine smoth all the way to redline, after i stoped i checked the tps again and it wasn't calabrated any more so i think thats bad |
I'd question if the TPS is good or not.
|
i don't think it is because it uncalabrates its self
