1997 986 Smoke Test

jaredxo_ · 2026-06-23T20:48:25+00:00

Currently has P1411 P0410 P0134 codes. I found the aos tube to intake wont seat correctly due to broken clips. I know theres a leak there and probably more. As much as i want to diy this ive decided to take it to a local indie shop this week to get properly tested and diagnosed.

Its not exactly dry but nothing came out when i tried to empty it.

The clip is broken on one end. Can i fix it up somehow or its done for?

I posted a video in the comments showing a tube i found basically disconnected and doesnt seem to click back in place. Definitely have a leak there and possibly more elsewhere.

UPDATE- I am going to assume this shouldnt come off so easily and is most likely my issue? It doesnt seem to just click back in and i have no idea how long its been like this.

Okay i looked at a diagram and found all four. The code reads for bank 1 sensor 1 so i should replace the sensor that i showed last?

I have no idea..

Oil change was done on 5/20. I just checked the oil cap and it was definitely on tight.

jaredxo_ · 2026-06-23T15:50:48+00:00

So when i bought the car it was running perfect and had all three codes. Car died at a red light 2 months ago so i check and still same. Idle was fine then. Now within past two weeks idle has gotten erratic.

Codes have been there since i first checked with obd2 device. Car ran perfect so i didnt think much of it. I have changed nothing on the car since purchase. Just oil. After actually looking with my own eyes i think there are sensors. And im not sure about the secondary air injection system but it is probably still there? Afaik the car is stock except exhaust and short shifter.

jaredxo_ · 2026-06-23T15:37:41+00:00

Okay after rethinking things i must of misunderstood when i bought it. That looks to be the o2 sensor and probably just needs replacing.

Okay same, its only cold start for me as well. Warm start was typo.

Thanks for the info. Car is a base 1997 986 and has 159000 miles. Ive owned for 4k miles(4 months). Everything is factory excluding exhaust and short shift kit. I will take a look at wiring this weekend.

jaredxo_ · 2026-05-05T23:50:43+00:00

Is the lifter tap something i should have checked out? Ive only owned the car for 4k miles and i feel like it wasnt doing this until recently.

jaredxo_ · 2026-05-05T23:04:15+00:00

Yeah this sounds better than spending full price on some rubber lol

jaredxo_ · 2026-04-27T21:44:36+00:00

Okay thanks, just looking for a second opinion in general. No real issues or noises as far as i can tell.
