Im working on a GEN1 lightning project. a litle feedback:
GEN1 LIGHTNING.
Engine: 5.3L ALL STOCK DRIVE BY WIRE
TRANSMISSION: 4L60E
This is the problem:
Right now almost everything is done exept the muflers, it only has the exhaust manifolds without o2s.
The truck starts perfectly fine
With the Scantool conected, on the dash tool i see how is she acting. everything is fine, the TPS% is on 6-7%, sudenly the idle sounds like if there was a cam on the engine and the TPS changues quickly from 7% to 2% then to 4% then to %2 then to %7, but fast, and then it returns tto normal idle and tthe TPS% stays again on 6%-7%.. what can cause the problem? i already changue the throttle body and TAC module..
I will atach a log, look close to the TPS from frame 3520 to 3620, again from 3703 to 3732
thanks for all
