Finished installing ARH LT's and ORY, LS6 intake manifold, and poly motor mounts, msd wires and ngk spark plugs. It was supposed to be a weekend install but turned into a month long project. The last manifold bolt on the driver side broke off into the head so i had to take the head off to get the bolt out and only working on my car on the weekends didnt help. After the broken bolt came out and the head back on me and my dad started to install the motor mounts, everyone's favorite install. The passenger side went in pretty easy but the driver side was a different story. After so many frustrating hours and unbolting the pedestal the mount finally went in. The headers just slid right in and the ory was a perfect fit. ARH makes a great product! The LS6 manifold swap was actually pretty easy and of course as expected i broke the opsu but im sure i wont have trouble with it in the future. Its been about a week after the install and the car has been running fine but there's something that troubles me, when i go WOT it seems that it doesnt pick up as fast as it use to and it feels maybe i lost torque somehow. I checked for leaks but every thing is fine and the spark plug wires are connected properly. Could it be that i just need a tune??

 

bump..

 

A tune sounds like a good idea!
Any codes, how the gas mileage?

 

cam it then tune it

 

How do you like the difference in motor mounts? Notice anything?

 

I pulled 2 codes: P0123 Throttle/pedal position sensor A circuit high input and P0405 EGR sensor A circuit low

I deleted EGR since i got "race" LT's but i dont know what the first code is..?

I did notice a difference with the motor mounts and im impressed with the outcome, there is alittle more vibration inside the car but nothing too crazy and i also installed the poly tranny mount cuz my stocker broke in half and my stock ypipe was banging against the undercarriage.

 

The P0123, voltage higher than 4.75 volts at wide open throttle. the normal range is .6 volts at idle to above 4 volts at WOT.
This is the TSP sensor on the drivers-side of the throttle body

Did you happen to do the TB bumpstop mod ?
Check the wires and the connector itself for a bad(broken, dirty)connection.

Or just a bad TPS sensor.

 

ive had a bad tps sensor before. and it didn't go bad till i pulled it off then put it back on.

 

TB is still stock but i went out to my car and disconnected the TPS connector and i found that a wire ripped in half so im gonna connect and crimp them back and see what happens

 

yeah....that probly wasn't helping u...just a guess.

 

lol i was thinking the same thing. When i go WOT it doesnt pick up as fast and never reaches 4K rpm's, connecting this wire should solve this problem?
