Thread: top swap, started engine, scans give me concern, help?.....

and i forgot to mention, after i unplugged the ECT and MAP, and it was idling perfect, i decided to drive it around the block, seemed to drive fine, no issues, gave it a 30% throttle and it accelerated fine and and 0 KR and the O2 was around 935.

i just want it to run right.

i doubt i had 2 bad ECT sensors considering one came out of the old 3800 that was in my car and was working fine.

i have to believe that there is a ground issue or a broken wire on the ECT part of the harness. there does appear to be a repair on the pigtail clip for the ECT, not the actual pigtail piece, but the main wire harness piece but it looks like a legit fix, solder and heat shrinked.


the map issue, could be 2 things...

1. 2 bar map just not working or not compatible with the L36 bin (for obvious reasons)
2. I may have spliced the wires backwards/in the wrong position on the connector. with the connect clip facing me, and left to right, it goes.... grey, green, pinkish for the wires.

and now since the ECT is unplug, the fans stay on anytime the car is on. which is better than the alternative.


and FFDP, thanks for the welcome. i'm in delano.

so i grabbed the connector from the 08 harness that i had and will be tracing back my 02 harness connector to the fault and then rewiring it.

i am also going to swap back to the 1bar 02 and 08 sensors. not sure why i even bothered with the l67 map in the first place since my pcm cant "see" the boost anyway. but in all the top swap threads, not one single time did anyone say anything about using the stock 1bar map, they only mention you "must switch the connector and run the l67 style map.

well, you DO NOT have to do that at all and you dont have to run anything extra. just pull out the L36/L26 map from the upper intake, there is a damn nipple on that thing, just plug it into to your vac/boost source and you are done. you may want to consider a check valve to keep the map from put under boost. not sure if you could source the vac from the tree on top behind the TB or not. but you certainly do not have to use the other style map or solder in the connector.

i will be unsoldering the other connector tomorrow and also fixing the ECT wire and HOPEFULLY, all should be well after that. i hope.
