Hey everybody I have a 1990 4Runner SR5 v6 3.0 that I just got running agian. I just put in new spark plugs and wires,new cap and rotor,new battery, and new mass air flow sensor. Before all that was replaced the truck was not starting at all. Now it starts but has a series of issues
1. No power on acceleration
2. Running extremely rich
3. Very low idle when engine is warm (400-500rpms)
4. Seems to shift gears roughly

I'd appreciate any help I can get fixing this I really need it running agian in missing the trails.

 

First thing you need to do is check all your vacuum hoses and then pull the codes.

 

Why was it parked ??

Have you checked the timing ??

Done a compression test??

Just how long was it sitting Bad gas ?? Rodent nests chewed wiring ??

 

It was only sitting for a week or two while I was working on it. I will run a vacuums leak, compression,trouble code test today after work am get back to you guys.

 

It's a 3.0 They all run like that.
