if its not vac leaks, worth saving up and getting a proper tune if it hasnt been. a tune is cheaper than a blown motor

If idle bounces, it can be because there is air in the cooling system, has it recently had a coolant flush or issue?

Sounds like 'hunting'. It usually occurs when either the tune is no good, or when theres a vacuum leak.

With the tune being no good, it says 'oh no im running to lean' and puts some more fuel and raises the idle, then thinks 'oh no im too rich' and lowers it.

Does the idle bounce around our fluctuate?

I would say bounces more often then settles

Hey guys!

I have a 1990 turbo and it has a high idle on start (around 2200rpm) once it warms it drops to around 1500rpm but at times also goes up and down between 1000rpm and 1500rpm.

I'm not that good on engines but I don't think it's a leak as I'm boosting around 8psi (not sure if this is normal or not). I do have a piggybacked EMS Stinger ecu so not sure if it just needs a tune or not? Any ideas?

Does anyone know anyone that can tune cheap? Can't really afford a full tune at the moment.

Thanks
