Anybody please help car bogging down

[Speach]

Man Ive got get this car going again quick. My wife is starting to want to get a new car and a payment with it. Not my style, Ive come to far with this car.

So a few weeks back my 93 wagon started kind of bogging down at a light. It idled fine but when it was about to get up to 5-10 it started stuttering. When I pushed through it it would run great at higher speeds. Also i am not getting any check engine lights at all. After driving it some more it has gotten worse and has started to leak oil.

What I have done so far thinking what might be the problem

- Not too long ago like 6 months I put a new fuel filter
- New Radiator with cap
- New cat converter pipe
- New o2 sensor
- Checked coolant and oil for mixture- no mixture present
- new timing belt/tensioner/water pump
- Took apart some of the out pieces of the intake and cleaned them, tightened down gently the small disc that people say to do when you have fast idle problems.

Someone told me maybe its a map sensor but wouldn't that bring up a code?

Thanks all for any help

I don't know what else to do

[deevergote]

What brand o2 sensor did you use?

[ts14]

try cleaning the the fitv and iacv. and adjust the fitv

Im pretty sure thats what I did, those are the things that come off the side of the intake right.

The o2 sensor came from Rock Auto, I forgot the brand name.

- Oh I also have installed a new ignition coil and dist cap and rotor.

when was the last time u did a tune up on your car?

[MrMagnificent]

Bogs at idle?

Does this occur when the motor is warmed up or cold?

Fitv usually is only a problem during cold starts.


I would look into properly cleaning out your Iacv. It needs to be super clean.

Other options you could try are TPS adjustment&replacement

I would go ahead and buy Ngk spark plugs

Change the old pcv valve while your at it

If none of those fix the problem it could be a dirty fuel filter or injectors

Oh and don't forget to set your base idle !!!

how long has it been since a tuneup?

new spark plugs, cap and rotor I'd suggest.

If your wires are in bad shape, then get new NGK blues as well.

If that doesn't take care of it, then adjust the ignition timing.

The o2 sensor brand is important. Denso or NTK is good. Bosch is bad. Any other brand may not be good. A failing o2 sensor will cause the engine to bog.

Yea I've got new ngk plugs sorry didn't mention that and new cap and rotor.

As far as tune up I think I'm good.

The car does this right after being warmed up. Its starts fine, idles fine at first and about five to ten minutes it started hick upping, its almost like its choking on something intermittently.

This is sounding like a bad O2 sensor or a possible plugged cat, cat's less likely because you changed it, but if you have already swapped in a denso o2 sensor you may want too check the cat.
I had a 1st gen eclipse with a bad o2 sensor that i never could find a o2 sensor for that did a similar thing when it warmed.

Egr system might need a good cleaning as well.

[kratemertyl]

cant he just try unplugging the o2 sensor and try letting it run in closed loop?

I put in a blank cat pipe just to not have to deal with it again and besides it was cheaper. I just picked up a whole intake/throttle body set up from another car for 40$ , This should give me more to work with.
