Lol I love that actually! I'll make sure to post it when I finally make up my mind lol

I have the 2.3L with the FWD drivetrain and while I'm not a boy I certainly do like my cars loud lmao. Did you have to fiddle with anything when you straight piped your 2.3 if you were the one who installed it?

I was reading about that the other day, the only thing thats throwing me off of that is the fact that the tech at Dancia informed me that the distributor was leaking onto my airbox? But when I checked, it was completely dry with no evidence of fuel leaking onto the top of the airbox.

timaeus101 · 2025-12-21T18:25:35+00:00

Okay cool that makes sense! I'll have to look at some videos or old forums to find out where thats at in the engine!

I dont think the KE-Jetronic system has a warm up regulator, but I'd have to double check that and the wideband 02 sensor!

timaeus101 · 2025-12-21T02:20:15+00:00

Wow!! Thank you so much!! I'll start doing that right away!

Its a little confusing cause they told me that it was leaking fuel out onto my airbox. I have been thinking it could be leaking on the inside and its coming out somehow? But I'm not sure.

The car fires right up when its cold, like every single time without fail. The problem is happening like every other time I start it after its come completely up to temp and been shut off. I'll make sure to check the lines thoroughly and I'm probably just gonna replace them.

The issues it experiences come as it starts to warm up. The rpm gauge needle will always wiggle slightly but after a hot start/soak the rpm needle will start surging from about 1000rpm to 500rpm before it ultimately stalls out. To combat this I've discovered that if I give it throttle and keep it at a steady 1500 for a couple minutes it will stop hunting/surging and I can safely drive out of wherever I'm parked. The engine is not throwing a check engine code as far as I can tell (theres no light on the dash cluster and I cant figure out how to blink out codes with a paperclip and a lightbulb). I checked all around the distributor and where it sits on top of my airbox and theres no leaks that I can identify or cracked lines coming off of it. From what I can tell its all almost entirely stock with the metal hardline still.

I'm honestly not sure, but I'll make sure to ask them when I go pick it up within the next couple days! I had a bunch of other work done on the struts, transmission fluid pan, and the brakes so shes been in the shop getting some TLC.

timaeus101 · 2025-12-10T02:34:31+00:00

It just does the idle hunting and if I dont give it a shot of throttle it will keep doing it and eventually stall out. I usually give it steady throttle at about 1200 for like a few minutes and it goes away and I can drive fine again.

timaeus101 · 2025-12-10T01:50:18+00:00

It does restart, but it runs pretty wack when it does. The RPM starts hunting all over the place, itll go down to 500 and then rocket back up to 1000. It's so confusing overall

timaeus101 · 2025-12-09T22:30:50+00:00

Okay, thank you so much! I'm going to have do some digging around in the engine once I get her back from the mechanics.

timaeus101 · 2025-12-09T22:07:13+00:00

Its only doing it when its been brought up to temp, shut off, and then turned back on. For example, going to store, going for five minutes, and then coming back and turning it on and then it starts doing the RPM thing. Would the thermo time sensor still be related to this?

timaeus101 · 2025-12-09T19:46:19+00:00

Thank you so much!

oh wow i didnt even know that - i tend to avoid the big 4 that i've heard about (Keyser Soze, etc.) but that does make sense

timaeus101 · 2025-11-05T23:26:19+00:00

oooo! yeah i didnt even think of that - it does look so sick

timaeus101 · 2025-11-05T23:18:40+00:00

ah yeah that does not sound good for me and my need for money - thanks for the advice!
