Hello, I own an 94 Ford Ranger 3.0 v6 4x4 ..

Before i got this problem I change the radiator, so i empty all the system, but it take 3 days before installing the new rad n fill the system,,

After that the idle was rough,,

I change cap and rotor,, spark plug and cable, air/oil filter,ECT sensor
the dealer was check for code, but nothing,, check my O2, masf, iac,,
the only thing was bad compression he said,,And check for new valves,,

I check the compression at another shop and it clean iac sensor:
Cylinder 1-115, 2-100, 3-115, 4-5 and 6-100....

this compression bad enough for my problem ??

If you have any insight or anything, please post it!!!

Hugo :scare:
