Can anybody tell me what might be the problem I'm tired of get motors after motors an I'm still having problems not sure if its the tune or what .

 

first off why is the engine light on? it sounds like rod knock.

what have you changed in the engine compared to stock? if you changed anything in the engine did you tune for it?

did you swap a sc engine in a non sc car and not tune for it?

we need more info about what your car is, what engine, mod list, and information on the check engine light or we would all be shooting in the dark and guessing at what it is.

how many engines is this? where are you getting replacement engines from? are you rebuilding the engines? do you hear the engines run before you buy them and install them?

 

Ok the mods I have are 40lbs injectors 3.2 pulley s1x cam ls7 lifters 105 lbs valve springs egr delete an Zzp tune with headers the problem when driving or sitting its struggling mainly while driving an then it will either cut off or stall out an wont cut on until I let it sit for a minute an I have to speed up faster an when I do I get codes 0327 0332 0134 0300or either 0303 0304 0306 or 0301 but no injector misfire I done change need 02 sensors new knock sensors maf an map new gaskets an all

 

did you check for good spark? did you check injector pulse? fuel pressure? compression? cylinder leak down? are you positive the cam in installed correct and the engine is in time? almost sounds like a timing issue.... do you have pics of the timing set installed showing the timing marks? when the cam was installed was cylinder 1 at top dead center? are you getting knock? whats your afr's? i dont have time to look up all the codes to see what they are but do you have misfires and if so is it a certain cylinder or random misfires? did you replace the cam and crank sensor? the fins on the harmonic balancer didnt get messed up did they? did you install the magnet that goes on the cam gear?

these are all the things coming to my mind right now... hope something in my rant helps you

 

Only thing I can think of is my timing sprocket has no timing mark its just -8 -6 -4 -2 - 0 +0 +2 +4 +6 +8 an that's how it's is on both front an back of the teeth So they said the set the timing off the first row of number it's just straight number it's from intense double roller set

 

This what they said about the sprocket

 

The crank sprocket gets set to 0 with 0 facing up. The cam sprocket has a dot on it. The dot goes on the bottom and lines up with the 0 on the crank sprocket.

Should look like this once installed

 

X2 sounds like a timing issue..That's what I thought when I watched the video..

 

Ok just example ain't the best but this is what my sprocket looks like doesn't have a timing mark at all its just numbers an right now it's set on +0 which is the outer numbers of the timing sprocket

 

That's confusing lol. What kind of timing set do you have? If its a JP timing set pull it out and sale it and buy a roll master. I've seen to many JP timing sets break!!
