When I bought it began overheating, my dad replaced the radiator and problem was solved. Now however there is another issue, the engine idles poorly and often stops completely upon start. It isn't powerful enough to drive due to this. My dad (who was once a mechanic himself) has replaced and looked at things such as the spark plugs and fuel injectors and I am beginning to get frustrated as the problem isn't solved. Do you have an ideas?

scan for codes, check fuel pressure with a gauge, auto parts rent it an dcheck for vacuum leak.
