My S2 has developed an issue when starting from cold

It takes around 6-8 seconds to fire, just cranks for a while before firing. And then it runs like crap

Ive noticed if i let it start with no throttle, when idling rough, Volt gauge is reading 10-11V... as soon as the engine settles it jumps to 13V

The car has had a service 2 weeks ago, new dizzy cap, rotor arm, spark plugs, HT Leads, Oil and Fuel Filter

I suppose it'll be better for me to go EFi as soon as i can

 

Sounds like you've covered the basics in your service, so it shouldn't be any of those parts at fault. I'd be looking at replacing the cold start injector and possibly the coolant temp sensor as I think this sets the enrichment for cold starting (anyone correct me if I'm wrong).

Failing that, like you said - go over to EFI. Would probably be the best option for the longer term!

 

Look forward to replies as mine just started doing the exact same

 

Go efi

 

Im more or less ready to go efi now, just need a few more parts. I'll try my best to solve this though for future reference etc
