Transforming my Alpine 325is

[Turbotalon92]

Also did some fresh rotors and pads all around and adjusted the height on rear coilovers to eliminate the rake.

So a few updates, mostly maintenance stuff

New fuel pump, my little girl helped me install.



Pulled the seats for a good cleaning and did some leather conditioner

So got the injectors in, much nicer power and responsiveness, old injectors had some serious carbon build up on the middle cylinder banks, much less to each end.

I have done about everything I can think off for on off load stumble and am scratching my head as it is still there. M20, new fuel filter, new injectors, new distr., wires and plugs, tested coolant sensor, and not sure where to dig next? It stumbles at idle, cold or hot, drives great under load, cold start is quick and sharp, hot start is a bit slower but not anything crazy long when turning over.

Thoughs?

Do your plug wires have the pickup wire on them? If they are E not I plug wires they won't have the timing pick up and it will stumble off idle.


Also check the AFM moves freely and is clean.

Looking good. I'm partial to the early Alpine Is though lol.

Rolled the front fenders today. Was quite easy actually.

Damn you guys are going to make me buy big brakes or turbofans before I can sort out my idle issue! :)

ICV, AFM, IAT sensor, O2 sensor? sensors galore!

This.

& big brakes yes, but painting stock calipers just kinda shows how small they are lol but you like it, thats all that counts

[Turbotalon92]

Thanks guys. A sensor testing I will go!

This. Also pull off your TB and clean it while you're at it.

Car looks great!

Valve adjustment 3 weeks ago. No change in symptom at all. Same before and after. I will double check though.

Other ideas?

That's what I was going to say... sounds like they are a little tight.

New injectors sitting in place

Thanks! I like calipers painted, it's an aesthetic thing just like all the other cars who have them, OEM or not. To your point, not sure there is any other reason than that, kind of like a painted valve cover or pinstripes?
