Default How to smooth out slightly rough idle

My rig is starting to idle a little rough, anyone have so ideas to fix it? Iv replaced the plugs not to long ago, replaced the plug wires the other day, put a new exhuast on. I was kinda low on oil but iv added some and plan on changing it later this week as well as changing the air/breather filter. Is there anything I can do? I also plan on doing the injector upgrade once it warms up a bit

1. Finish that tuneup! You need a fresh distributor cap and rotor as well. Stay away from Bosch plugs.

2. Cleaning both the idle air control and the throttle body is recommended

How much would a new distributor run me? Are they hard to change out?

Not the distributor, just distributor CAP, which installs on top of the distributor. And under that cap is a ROTOR, which just slides onto a shaft.

Get a new distributor cap and rotor. Money well spent. Ask for a cap with brass contacts. Better than the aluminum contacts on a cheap distributor cap and only a few bucks more.

Very easy to replace but it is very important not to mix up where the plug wires go! So label them or do one at a time.

Re-read reply #8. Easy to install. A couple of screws hold the distributor cap on. When the cap pulls off, the rotor will be visible and just slides on and off.

yea do the cap and rotor, just a few screws pop on and off, 10 minute job. they are like $20 for both.

ALSO FUEL FILTER!

Take the intake boot off and spray and clean the intake out really good, preferably before the new injectors so the dont get crudded up. as said take out the Idle control valve and clean it
