What do you hope to accomplish with the TB swap? You are throwing unknown quality used parts into a system that already has issues. |
I haven't. For some reason the Code Reader doesn't work on this truck. Last time I plugged it in it wouldn't read the ECM. If it did, I'm sure I'd have a better idea of what's going on. Check engine light also doesn't come on.
Thanks, pretty informative videos. I still have to get to the 2nd one. Looks like the possibility of a vacuum leak can be causing this too.
Looking to get it to run "normal". Of course they have been sitting a while but the TBI came out of a known running truck that ran strong but the frame/body rotted out.
What would you suggest? I'm assuming you saw my other thread so you know what has been replaced on this engine/system so far....
