Re: 1990 Cherokee won't run over approx. 1500rpm
Thanks for all about the replys !
It is import model, i live in Finland.
I added extra ground cable from head to the firewall.
CPS wires are ok (not melted),i replaced the wires some time ago.
Exhaust/catalytic is not clogged,but i'll take a closer look.
I havent check manifold vacuum or fuel pressure yet.
Fuel filter,distributor rotor/cap are on the list to replace,right when
i can get them.
Where is MAF sensor located ?

Hmm....
In my book, the distributor cap, rotor, and the fuel filter would be the
'first' things to replace, not the last.....
You could have a 16 year old distributor cap in there and I will bet the
fuel filter 'is' 16 years old....
My 88 bogged down like that once. When I went to replace the fuel
filter, it literally crumbled to pieces.
The MAP sensor is on the firewall center on those I believe with one
vacuum line running to it.
