I have a 83 Porsche 924 2.0 that I cant seem to get running right. Its lumpy on idle and its not pulling very well. It rev's out but feels like its off, its definitely slower than my other 924's. When she warms up full at idle its almost like its timing is slightly off. I checked for vacuum leaks and it looks good.

Any ideas? I have a quick video of it below (although its hard to tell in the video)

I would try resetting all of your timing. It sounds like your ignition timing is off a little bit and your not burning all the AF mixture in that chambers. Make sure that you ignition timing is set so that the distributor rotor is pointing at the scribe mark on the distributor.

Check your plugs too, they may have gone south on you.

I would try that first so at least you can rule out timing issues, then go after the daunting task of figuring out vacuum leaks.

could be timing or running lean, check your mixture isnt set for too much air

Just a follow up guys, turns out it was a gunked up fuel filter. Fuel pressure was down by about 50%. Replaced it for 40 euro and we are good to go! Thanks for the help!

Cheers

Now onto replacing the steering rack Once that's done that's most of the major work done. I can do the minor stuff and the car should be good to go!
