there is a small update, i took a look at flyweel from the small window between the oil pan and transmission, it's stock and solid, and has no cracks.
but the weather is dry and warm finally and we made a test drive.
this is first time i drive a monster like this and... it wasn't impressing at all. if the truck was 3.5 i would say it drives nice but... it's not what it should be. i was trying to make my own opinion without paying owner's complain attention, thinking that maybe he just wants more power but now i changed my mind, this is not the case. it runs like 150 hp honda, hardly making 130 on 6th, a bit better on 5th. owner says that the truck was accelerating nice after reaching the end of speedometer.
with tires warm after drivig is inpossible to burn them with only pressing the accelerator on 3rd, tires are old maybe original ones.
it would be nice to hear from you how your trucks behave
pilot bearing may be an issue, but not for highway lack of power i think...
as i know the only thing ever made on the car was removing original exhaust, putting something garage-made and after 2 dissapointing days refitting the original, and probably this is the point in time when problems started.
yesterday, while thinkig what could be wrong, came to idea to check if O2 sensors are positioned correctly, this is only thing (i thing) that can be wrong while reinstalling exhaust, meaning 1st bank sensor connected to 2nd or so...
also noticed gearstick kicking a little around 2500rpm at 6th and full load like cylinders missfiring, so finally it may be some issue with ECU, knowing plugs, wires and coils are new and triple checked. wire loom also checked completely, not only at 10th cylinder corner
, it's made from silicone insulated wires (like in ovens) and i thing it should resist even if it fells on exhaust.
i'm out of good ideas, i see the problem, i feel it but can't figure out what's causing it. i feel comletely like accounter, not like mechanic
shame on me
any idea appreciated
