Has anyone had any issues with their o2 sensors(front obviously) not heating up or heating up to much after LT header install(specificlly coated Pacesetters)?

What codes are you getting. I have PO 1133/1153 probably due to not heating up enough with my LT's.

after installing my pacesetter LTs and ORY i haven't had a single problem with 02s, either set. i haven't even thrown an SES code for the rears and i don't have 02 sims OR tuning to turn them off

Nah Pasesetter hasnt got off their *** and made them fit 4wd's yet. Saw Hookers are suposed to fit 4x4's though? Hmmmmm. More options coming available, Pasesetter better hurry up.

Here is what is happening. The dtc I keep getting is p0200(injector circuit malfunction) but I have the o2 dtc's turned off. Basiclly when I crank the truck in the morning it idles horribly like it wants to do. When I start to drive it its does the same(basiclly undriveable) thing it starts to load up and sputter but if I put it in 2nd gear and get into high rpms for a few seconds then put it back in drive it goes away mostly. Then sometimes if I go somewhere and park it for a 20 minutes or so and come back everyhting is fine other times its back to idleing horrible. It feels like when your running with 7 spark plugs except it has all the power it just doesnt want to open up and for the most part up in high rpms is great. I dont have any exhasut leaks,no bad plugs,wires arent touching the headers,and I just replaced the o2 sensors a few days ago. Ive cleaned the TB and made sure all the injectors are connected. I do have a descreened stock MAF(been descreened for a year) and saw where people have had issues with LT's and aftermarket and descreened stock MAFs but I havent seen any DTC's about it. Alot of the F-bod guys have troubles with their o2 sensors(front) after LT installs where the 02's werent heating up properly and staying heated up becuase they are farther away than stock. I dont know what this is but Im gonna clean the MAF and turn it a bit and if that doesnt work im gonna bring it in under warranty( ) to get a new one. Im also gonna try some header wrap,and if that fails im gonna do the vette 02's(they are higher volts and heat quicker supposodly),and if that fails I guess Im gonna have to move the o2 sensors up a bit and if any of you are familiar with the Pacesetter LT's there isnt but maybe 6 inchs to move them up so I dont see that working. Help! Oh and byt he way the LTFT B1 & B2 are reading almost the same as well as the STFT B1 & B2 so the 02's are good.

With an injector circuit malfunction code I'd be checking out the connections at the injectors. 1slowhoe had a problem where the wire terminals were spread out and not making a good connection...not sure what code he was getting but I know it drove him nuts for a while.

couldn't you just put a set of sims in the place of the 02's

I have already removed the rear (2) o2's and have them turned off on the PCM the ones I am talking about are the front (2). I guess techniclly I could remove them and not use any 02's but I dont want to got hat route!
