k jet injection question (924)

[baggabones]

Car is eventually starting fine hot and cold after reworking some PO bodges however,my problem now is that on cold start she only runs on 3 cylinders for the 1st minute then all is fine again?...leaking injector? Or ignition or something else? Ta

Think you answered your own question already hahaha

Get em out and in glass jars overnight if you can all still plumbed in
Culprit will soon become evident !!

Much more common on diesels like those pesky tdci things lol

I would be tempted to remove the aux air valve ,give a good clean with carb cleaner and try it from there.
It may not be opening fully on a cold start, thus running a bit rich on cold start.
My 1983 924 n/a has never had a hot/cold start issue ,but ive seen enough threads to know it can be a hard problem to fault find!!
Good luck

Hi there

I run a 1982 924 lux and now and then it does the same thing. Definitely a leaking injector. It usually starts fine but every once in a while it runs on 3 for 10-15 secs.

Not really and issue.

Many thanks for the replies, have a full set of spare injectors that i've put through my ultrasonic cleaner and replaced the seals, so will swap all out, either tomorrow or monday when i'm off work and do aux air valve as suggested cheers for the help
