My SS & dead stop after cam swap + tune !! :(

**Sayed_000** · 09-19-2009, 04:42 PM

I did full over-roll for my engine & a cam swap

Changed/Replaced :

all Gaskets ( heads ,intake ... etc)
Cleaned the MAF
ls1 water pump
ls6 oil pump
Ported the Stock TB
air/fuel filter
plugs
cam w/specs ( 230/236 112+2 LSA)
Tuned

And am facing idle problems specially in 1st gears with a low RBM .. the RBM stay stable at idle but in driving the car go to Dead stop Just like it's need to be re-tuned and i did the tune more than 3 times ! and the problem still appears ..

specially while driving w/ A/c On

Anyone?
it's killing me

Forgot to mention

sometime it gives me codes like:
P0201
P0300

and the idle rmb after tuning is 820~850

what are you tuning it with?

Am not very expert in tuning so i took the car to 3 different Shops to do the tune for me
and still Same..
Is that cam really big For the DD or The street ?

No the cam isn't the problem, were the people proven lsx tuners?
The tuners should have told you what those codes are.

p0201 is an injector 1 control circuit dtc and p0300 is a random/multiple cylinder misfire dtc. Might want to look at that number 1 injector and wiring first and see what's going on there.

I'm going to check the injector and I'll try to clean them ...

any other suggestions ?

You need to find someone who knows how to tune. The problems you are having (from the tune) should be simple and you need to find what's going on with cylinder 1 injector.
