Im through scratching my head, I need help!

After a few miles of interstate driving with speeds around 60-75 mph, my truck starts sputtering really bad when I stop at a red light. Its a 95 Tacoma 4x4 5spd 2.7. The truck runs fine through out the city in stop and go traffic after this happens. Only happens when at idle.

 

K.I.S.S. (Keep it simple stupid). What my dad taught me when diagnosing problems with just about anything. Start with the simple things first. Fuel, air, and spark.

Fuel (check filter and pump)
Spark plugs, wires
Air intake (filter, MAF)
Check all your vacuum lines as well.

GL.

 

Is the check engine light on?

 

Im clueless when it comes to vacuum lines. Whats the best way to check them?

 

If its an idle problem maybe check the idle air control valve

 

No check engine light.

 

With your eyes….

 

This too. I wash't too sure about it having one. I'm not too knowledgable on any models earlier than 2001.

 

Might be sticking fuel injectors. Try some injector cleaner in the fuel tank. If you have a stethoscope, at idle touch each injector and listen for it ticking; no tick = bad or stuck injector.

Clean the MAF, too.

Good luck

 

I think I can give a shot if thats all it takes.

 

Sounds to me like I have alot of work ahead of me tomorrow. I will report back when I find or dont find the problem. Thanks for all the feedback!!
