Thanks guys for the advice. I will get the codes read and go from there. I will call Mike on Monday to get a status on the chip.
Happy Thanksgiving to all!!! Steve |
I got a code reader last night and got the following code for the Check Engine Light.
P1131 Lack of HO2S1 Switches -Lean (Bank 1 Sensor 1) I looked it up and it shows it could be the forward O2 sensor on the passenger side or to check the PCV connection and vacuum lines for a leak. I don't have any clamps on the lines right now as I am still working on making brackets, so will have to try clamping all lines and check the connection of the O2 sensor, then see if I get the code again. I also spoke with Anita at Troyer yesterday. She said my chip order went to Superchips on the 19th of Nov. so will be another week before I have it. Anyone else have any suggestions for the code I have above? Thanks, Steve |
Steve,
The code indicates that the PCM is trying to correct for an overly rich condition. The diagnostics says to: Check intake air system for leaks, obstructions and damage. Check air cleaner element, air cleaner housing for blockage. Verify integrity of the PCV system. Check for vacuum leaks. Once all these check out the next step is to check out the MAF. Did you get a MAF for the 5.4 or are you still using the one for your old engine? JMC |

Thanks for the info. I know I need to clamp all my hoses on the intake connections. I am sure there are leaks as I have one hose which is short and once I replace that with a new one, I can clamp it properly. That should clear the condition. As for the MAF. Per my conversation with Mike Troyer, he said to stay with the original MAF and he will have the chip programmed around that. I will try check all the connections tonight and see if it changes. Thanks, Steve |
Just an update.
I clamped all the vacuum lines and pvc and made the bracket for the EGR. Took it out for a drive (not the best night to do that as it was in a snowstorm). Drove about 8 miles and no check engine light. I still get a little vibration around 1000 to 1500 rpm which is right about 55-60MPH. I am guessing that is still tied to the lean condition. I should have the Superchip next week so am hopeful the performance will be much better. I can really tell the difference in torque. I will post again when I have the chip installed and know how it runs with corrected programming. Steve |
I have an 11,000 mile, 2002, 5.4 takeout. I swapped my entire powertrain for that from a Lightning.
Engine, Trans (with mild shift kit), wiring harnesses, PCM, EVERYTHING you will need to make the conversion. It is in excellent condition. I may even throw in the driveshaft for a Supercab. E-mail me at madferraristi@msn.com |
Ok, so I have another update.
The check engine code P1131 was being set by the passenger side O2 sensor. I replaced both precat/front O2 sensors tonight and drove20+ miles and no code. Talked to Jim at Superchips today about my chip. He wants me to get a dyno run on it to get the AFR at cruise and full throttle. Yipee....I found out there is a place in Des Moines - local for me - that just set up a dyno. They will do a single pull for $50 and for an hour $120. Will try to get that done next week. Mike Troyer asked me to send the info. to him and he will forward to Jim. Then I should have my chip and will know the true performance of this motor. Will post more when I have the dyno done. Steve |
Had the dyno run today.
After thinking it was running lean, it was exactly the opposite. It is running extremely rich. On the HP Pull, AFR was between 16.06 and 16.24. Max Power at 4000 was 116.9 and Max Torque at 3250 was 161.8. I also had a pull at cruise and the AFR was running about 17.00:1. It should be running more like 14.65:1. I think that explains the miss and vibration at lower rpm. I will be faxing the results to Mike Troyer tomorrow and hopefully will have a chip by next week to run. Mike also indicated the 1998 4.6 with my PCM code is hard coded to a 4.6ci and they will have to program for the 5.4 Will update next week when I have the chip in. Steve |
with AFR's in the 16's. That seems a little lean to me for a N/A engine. Shouldn't the cruise AFR be closer to 14.7? (edit oops you already said that)The lower the number the richer the ratio. ex: a AFR of 1 would be one part air one part fuel.
ps. awsome thread! Jes |
OK, so I'm confused. Is 17.00:1 rich or lean as compared to 14.7:1?
Steve Nevermind! I found out it is a very LEAN condition. Won't be driving it for sure until I have the chip. |
17:1 would be lean. Stoicic is 14something:1. So yes, that's running lean.
I could be wrong but WOT should see something like 12.5-13:1, or slightly rich. But what the hell do I know... maybe ask an expert like Neal the HP freak. Great thread BTW, learned a lot. |
Just wanted to update you all. Since Mike is out with the flu, I am waiting on my chip. He will be doing the programming next week if he is back to work. Once I have a chance to drive it with the chip I will add to this thread.
Thanks, Steve |
:thumbsup: :lurk:

im keeping tabs on this too. Very interesting thread going here.
That vibration does it happen when the tranny goes into OD? When was the last time you had the tranny fluid and filter changed? I know it "shudders" once it goes into od if the fluid is going bad. Could be that. Can you give a total parts list when your done? Like besides the motor what else did you have to get? |
I have not been driving it yet due to the extremely high AFR. Mike Troyer and I talked on Monday and I have ordered a copy of Autotap software with interface to do some data logging. Once that is done, Mike will be able to burn a chip with a base lavel to start performance tuning. The dyno facility I used here really messed up the run and I will have to have it run again when I can drive it.
As for costs, I will see what I can do for a list of what I have in it. I will also change out the trans filter and fluid. I had but in a BBK shift kit a year ago, but only put 18k miles on it since then. Would not hurt though to change the filter and fluid. Getting closer. Just wish Mike had not been sick for 3 weeks. Oh well, good things are worth waiting for. Steve |
