Hi all, im new on here and wish I knew this existed a long time ago!
I recently pulled down our 1985 gtv6 2.5L to put all new gaskets and seals in it as it leaked like crazy.
Got it all together good and started fine etc, but once up to temperature, it starts revving up slowly to 1800 then dies to 800 in a cycle that takes about 4 seconds. Iv cleaned air idle valve etc, no idea if somethings not working properly or what.

Also when it idles its fine in regards to firing but when driving, light throttle is ok with a slight miss, half throttle has a definite miss, full throttle has a slight miss. Cant sort it, timing is good, fuel is good, have put injector cleaner in it, all to no avail.

It did sit for 2 years pulled apart though
Any ideas would be great!

Are you aware of this page that walks through checking out the L-Jet?

L-jetronic Fuel Injection Technical Troubleshooting Article

Sounds like a couple possibilities from your description. I'd check for air leaks, the obvious with the hoses but also the less noticeable in the accordion hose connected to the intake. In addition you should check that the Throttle Position Sensor (TPS) is correctly adjusted. Check the that the timing is set accurately and that the distributor is tightened down.
