My car is intermittantly falling on it's face (bogging) @ roughly 3k RPM... in any gear, can be while crusing, while accelerating.
i.e. accelerating from a stop, bogs at 3k.
i.e. crusing at 3k, part throttle on & off, and then suddenly starts to bog.

I tried cruising at a higher RPM, i.e. 4k RPM and it bogs at 4k intermittantly. I didn't take it much higher than that in to reduce any damage it may cause.

If I pull over, and restart the car, it drives normal for a little bit, and then will do the same thing again. While cruising, I just key on & off real fast to reset it (like when you're tuning and have the reset the ecu for updates) and it will drive normal again, but only for a little bit.

I changed out one of my injectors yesterday (used) because it was leaking fuel onto my intake manifold. Could an bad injector cause something like this to happen?

Any help would be appreciated.

 

is this a turbo setup? when i put back on my turbo setup i forgot to do timing and when i would be driving around same rpm as you my car would bog really bad and couldnt drive ....did you check ur timing?

 

it's not a turbo car... but it drove fine for over 100 miles before this started happening. I'll recheck the timing, just in case.

 

try checking if its the TPS, a clogged fuel filter can cause the problem too but it might not be the fuel filter if you turn it on and off then its fine for a bit

 

Is it possible that this has anything to do with the injector I swapped out?

 

possible, but im not sure

I guess what I should do its swap out the injector again and see if the problem persists...

Another person mentioned that my symptoms resemble his previous experiences right before his ignitor died...

 

the last time i had a problem with this was with my distrib. if you have another one or can borrow another one just to test, it would be a good idea

 

Shout out to ndogg for his help. It ended up being a Bad O2 sensor.

 

wow i ran my car without o2 sensor for 5 months i think all it hurt was my gas lol thats cool least you fixed ur problem

A few years ago my car was stock and I had the hardest time passing smog... every other year here in MA. I ran on a bad O2 for probably the full 2 years... hopefully that's all it hurts, gas mileage... it's not like I'm breaking in a new motor and have to worry about running too rich. I have never seen a CEL for an O2 in my car. I even cut the signal that goes into the ECU, still no CEL.
