5.3 swap into 1990 chev truck
Background info, neighbor had a shop install an LS in his 1990 chevy truck. He gets deployed, truck sits, he returns from deployment shop says they went out of business. Fast forward 5 years. I say let?s look at it. Wiring is a mess, but it is an aftermarket harness, nicely labeled. I install a fuel system, run some power, get it to crank, and after adding a few grounds here and there it runs.
It will crank and sputter a few times, and then fire up, super high idle, popping out the exhaust, and finally after about 30 seconds or so it?ll settle down into a 700-900 rpm fluttering idle.
If I press the accelerator it?ll jump up to 6k with no effort, and then again settle down to the erratic idle.
I?m a newbie to hptuners, so still learning the lingo and whatnot. I am not a newbie to tech stuff.
I have found no vacuum leaks, looks like all the sensors are working correctly, o2s seem to be doing their job, I can?t get this to idle.
The previous place did a ?mail-order? tune and ive looked through it and don?t see anything out of the ordinary.
Fuel pressures are correct.
Wiring/grounds all seem to be correct.
Please any suggestions greatly appreciated.
Thank you,
