ok i have knock

[typhoon fever]

I don’t have knock in first gear ever, only in second and on.
Would bad vac lines or a bad cat cause this?
Because sometimes the truck will idle a lil rough then others it will run way smoother
I know it’s not the gas because I have gone thru 2 tanks of 91+ a 10$ octane booster

Also I thought my thermostat was bad because the temp gauge wasn’t going over 120.
So I changed it.
The gauge is still not going over 120?!!!!!!!! :rant:

what do i do to find the prob

Re: ok i have knock

The stock gauge doesnt read temp well. You have to look at Datamster to know what it reallyis. How much knock do you have nad how are getting your information? Can you post up a run? Or email it to one of us?

Got Datamaster?

Knock (real knock) is bad gas,wrong plugs,high intake temps,timing issue,bent rod broken lands ect.

If it "knocks" at idle with no audible rattling sounds,chip isn't set right in the carrier.

How do the plugs look?

Re: ok i have knock

Are you driving in OD or D (TCC lock up problems in OD?)

If I'm not to old and still to x-mas drunk I think I read that the temp sensor in the driverside head is the one that the guage uses. I'm not 100% sure.
(someone here will probably know for sure).
Thermostat is prob working OK.

If you have the autopart store octance booster, those raised the octane only a fraction of a point. You might only have 91.2 octane in your tank. If you want real octane booster you need to mix up a batch of Xylene.

Correct - green single wire.

ECM takes one off the front of the block near the thermostat.

I agree get yourself some higher octane fuel.. these trucks weren't ment to run on 91 from the factory so that may be your problem.

Throw some higher grade in there and see what happens.. most likely the kr will go away and if it does then you know what you must do


Also.. check your connection or replace the coolent sensor in your driverside head by the exhaust manifold.. like stated above it's the one with the green wire coming out of it.

If its real knock, first gear night not be loading the engine enough. My truck with its knock problems happenned intially only at the top of first gear like at 1-2 shift. I thought it migh be transmission/Torque converter noise I relocated the knock sensor to the front of the intake, it just delay it a half second.

Also how knock spark retard are you gettting?

There are two types of pitbull chips... a street version and a race version. The race version required 40lb injectors I believe. The street required 93 octane and that it. If you look through the little window on the blue cover of the prom chip it'll say what it is and what model.. I believe street chip was sy138a

I wouldn't think the pitbull would be your reason for kr as it's basically a stock chip with a few limits raised or removed. It's the closes to stock and safest aftermarket chip out there.. also is 2bar like stock chip. Many have ran them with stock to bolt on trucks without issues.

Don't know about the pitbull, but I know the ATR has the stock prom plugged into the 'side' of it. The stocker has a blue plastic cover. Remove the stocker from the pitbull, then reinstall just the stocker.

The pitbull chip didn't piggy back the stock prom at all.

Stock injectors it's for then I would guess.. so it's most likely the street verison
