Ford truck xlt ranger2.3 litter oil in throttle body ? good or bad

I found out with my old 94 Ranger 2.3L that the oil breather does not have a filter element, which causes oil to "naturally" (as Ford puts it) accumulate in the throttle body and air intake hose. You can get an inline breather element at any parts store for a few bucks and install it on the breather line without harming anything, and this will stop. Cheers.

1995 GEO-PRIZM 1.8L eng.Surges under all driving conditions

If you have a check engine light on you can pull the code and it should tell you if its an o2 sensor or not. I usually replace them when i do a major tune up. Change your spark plugs, wires, cap and rotor (if your car has cap and rotor), oil and filter, tranmission oil and filter, air filter, fuel filter, coolant flush, and o2 sensors. Thats a major tune up. Also spray a little brake cleaner above the engine around the intake and vacuum line and see if the engine reacts to it. If does you have a vacuum leak which may cause you to surge aswell. You may also want to change your iac motor and throttle postion sensor aswell seeing as they have alot to do with idle and acceleration. Without an engine code its hard to tell but those are my basics gor that problem. You can ask a mechanic for a diagnostic then you can fix it yourself if thats what you are trying to do. Hope this helped good luck

1996 Geo Metro LSI 1.3L Has issues starting. It cranks but won't turn over just replaced it March 2 2013

Check your battery connections at the starter. It may not be getting the needed volts. Just make sure they're clean and tight at the starter and the battery both. Good luck!

Going through oil lots of smoking oil in air filter

The "tube" from your oil fill to your breather should heve a n either metal or plastic piece in it . if you remove it and shahe it it should rattle , that is the one way check ball (no rattle = no good) this part is called the PVC (Positive Crankcase Ventelation) The lower end of your motoe needs to be vented and this is how it's done. Now that I've explained a little how it works ......the bad news , if you'r getting a lot of oil out of this into your air filter, you most likely have bad piston rings : ( If on a budget and cannot afford a new motor or get that one rebuilt you can unhook it from the air filter box and make a "catch can" and run the "pipe" which I'm assuming is a hose into it (so it is not dripping oil on your motor . It will buy you some time until you can get it fixed properly .

1994 Metro Geo rough idling and lagging up hills

dunno if it'll fix it- but check your pcv valve - 5$ for a new one - also check your egr valve- should be able to move depress it with your finger- if not, carb cleaner is safe to use to clean it up- remove it and clean it. this should help the idle

Heavy smoke from air breather and surrounding connections

when was last time PVC valve was changed?
and is there oil in the air filter or in the throttle body?
and if there is this is maybe a sign the blow by on the oil rings is getting weak before you go crazy go to napa or auto zone and get Lucas oil treatment and try putting a quart of this in instead of a quart of oil at the next oil change and this may help you out
