Timing chain and gear could be worn, but first try premium fuel for a few tanks

Well unfortantly the ethenol isnt any good for your vehicle what your hearing is experiencing is a pre ignition knock it poor fuel and unless you can find a station that offers ethenol free fuel you will continue to experience it the other thing you can try is get a bottle of sea foam ful system additive dont use the entire thing on one tank fill ur tank just put a quarter to a half a can in see if it helps at all and good luck

Where is the knock sensor for my 96 isuzu rodeo v6


YAEEH (yet another easter egg hunt)
why do you ask. scan it and it has DTC for knock? nah, bet not.
be best to scan it, no?

usa RODEO.
GM V6 engine with their own 3.2-liter 24-valve SOHC V6
LG6 , i think ended in 1992.
or
3.2 L 6VD1/6VD1W V6 (bingo)?

YAEEH
ill toss coin, land on 6vd1

some dont have a knock sensor. the 2.6L does.
the 1998 6vd1 has one, but not 96, in usa.


I even looked at your ECU/CPM schematic,
for the V6, and it shows, no knock sensor,(usa spec car)
The EFI spark system used on your car dictates this.
as knock (KS) controls spark timing, (retards it at knock)
but some versions have no KS sensor.

if fitted its on the block top.
has 1 wire. and screws in on a simple stud .
some are under intake manifold
its just a threaded shallow hole in block,
its only a microphone device.
here is the block a real photo.
some have it , others, dont
and one more fact, it came 92 and went and came.98
facts.

clear? see red circle below?

Head gasket or intake manifold gaste again 96 k1500 5.7 vortec. starts runs idles and drives rough it likes to **** while trying to drive almost as if it wants to stall out. i put my scanner on it and


The website has software that looks for obscene words.
I would think a compression test would show if the cylinder is having mechanical problems. And yes the intake or head gasket could be leaking again, especially if the intake or head were warped or cracked.
Have you checked fuel pressure ?
Does the spark plug for cylinder 5 show signs of coolant leaking into the cylinder ?

I need engine torque specs for 96 vortec 350 please


Best thing is to go to your local parts store and get the haynes or chilton manual for it, and it will have all the specifactions.

It could be a faulty fuel injector, try running a fuel injector cleaner through your fuel system. At worst the poppet nozzle has gone bad and will need to be replaced, you can buy the poppet nozzle it self individually at Auto Zone or buy upgrade MFI system which is much better and less pron to fuel leaking room a cracked poppet line or nozzle which will cause what you have described.

Engine runs extremely rough, seems to be fuel related, new fuel pump & filter installed, pressure good, run 2 bottles of injector cleaner through. Can't get to stay running under load. 1998, chev....


Have you changed the plugs, if any are fouled out or if any are worn, it takes more to fire it under load and may be spark knocking because one of the plugs can't fire off all the gas and cause it to skip or idle rough.

I have a 98 k1500 with 5.7 350 and it wont start, has spark and fuel at the tbi but the injectors wont fire, will run on ether if sprayed down the tbi any ideas


have the fuel pressure checked ,im assuming it is a vortec,
you need about 55 psi continusly to keep it running, i have a 96 2500 sierra. the fuel pumps were known to be terrable in these trucks. i put a new one in, then had to remove it to replace it again amonth later, they are flawed by manufacturing design.

Timing is not adjustable. You do however need to turn the distributor to set the cam/crank correlation to keep the check engine light off. Although you need to hook it to a scanner to be able to set this.

Sluggish '96 chev 4x4


id start off with a basic tune up..you never know when u first buy a car when this stuff was lasted checked up on..i would first change the fuel filter if its clogged its really going to slow you down..then i would do and oil change to it and maybe the plugs and wires..check all of the fluid levels especially the transmission fluid..if you want to add horsepower and performance i would put better oil better wires and plugs and maybe a k&n filter instead of a paper one..
