Hi,
I own a 91 Dodge Spirit, with a 2.5L Non-Turbo "TBI" Engine - For a while the car would just seem to die at random, whenever it was warm outside... I've replaced the fuel pump, fuel filter, Oxygen sensor (since the computer spit out a o2 sensor shorted code), and even got the MAP sensor tested at Autozone. It stopped dieing at random like it was. Now it's like this:: The car will run great for a while, and at random will just bog down, total loss of power. It seems that the further that you press the gas down, the more it wants to die... So this tells me it's got to be a air/fuel mixture problem.? Sitting in park, you'll be lucky to get the RPM's above 3000. I looked in the barrel of the carb, and see fuel sitting atop of the butterfly. If you let the car sit for a little while... (about 10-15 minutes) It will be fine again, and have all of its power, until randomly it acts up again! (Usually about 30 minutes of driving it at highway speeds) -- Don't know wat else to do!! Geting tired of buying parts that dont fix it. - Thanks in advance -- ALSO, was wondering if there is a computer that I can hook upto this Vehicle... to find out what is going on. I guess its a "OBD" system? I went to Autozone, and all they had was an OBDII tester, that doesnt seem to connect to my car anywhere. :) Shall I rebuild the throttle body!? --

This reminds me of another thread I saw awhile back with a car with a similar problem. I think it's the hall effect thinger, but I'm not sure. This goes nuts, and you push the gas down and it dies. You go to check the carb and it's full of gas, since you just flooded it by pushing your foot down when it was dying. That's what I think was happening. Is it called a hall effect pickup or something? This hasn't happened to me before, and I don't know much about it. Slantsixness or someone else should know something about this...

Check your comp[uter codes.

Hall effect (distributor pickup)
TPS (throttle position sensor, it's on the throttle body...)
fuel pump relay.
Temperature sensor. (unlikely, but it'll F#$% with idling.
crap in the fuel tank.
It's almost never the O2 on a 2.5


Check these. it should throw a code for the TPS

Yeah I reset the codes, after installing the new O2 sensor, and the car was bogging again, while my girlfriend was driving to Colorado Springs. -- When she got the car back, I checked the codes... and nothing but a code 12, and 55 -- which is normal.... Go figure... Thanks computer for telling me whats wrong with you! You mentioned the distributer pickup? Hall Effect? Where exactly is this located? Is it like a knock sensor, mounted on the block? Or is it actually inside the Distributer? I've replaced the rotor, cap, wires, plugs recently... Thanks guys... I am thinking maybe I should take the fuel injector out of the throotle body and inspect it... OH yeah... What would the fuel relay have to do with this problem? and where is it located? On the drivers side fender? --- Thanks in advance... again..

The hall effect is in the distributor, under the rotor.
It just pops out with the rotor out.
It's your ignition trigger, and nothing at all like a knock sensor on a GM...

It could be your TPS (throttle position sensor) even though it doesn't throw a code. the TPS is mounted on the throttle body.

Fuel relay is in the "fuse" panel near the battery. It can develop poor, burned connections internally and intermittently shut off the fuel pump. It can be a S.O.B. to find bad, but it's cheeeep, so just replace it as a precaution.

Slantsixness

A new development... The vehicle still completley dies at random, and ya let it sit for awhile... and it starts up and runs fine again... This time something threw a code... "No signal from Speed/Distance Sensor" Well this seems to be an itermittent thing, because I'll clear the codes, it'll die, and then I get no code.... Would the speed/distance sensor - Cause this kind of behavior? The sensor will cost me $50.00, but if this is not something that will cause it to bog, and die - I dont really want to spend the moey on it. (Like the Unecissary O2 sensor I just replaced)-- BTW... I took the hall effect sensor off of the distributor -- It actually looks fairly new, and I could not see anything that would cause it to be malfunctioning, (Checked the harnesses as well) -- I will replace that fuel pump relay just in case... as well, cuzz it is cheap to do so. Thanks again guys...

the hall effect is cheap too, and you probably wont see a defect in it visually.

Same for the TPS.

The speed/ distance sensor shouldn't cause the car to "die", but check the harness to the transmission for damage/ loose wires. You can even pull the speed sensor out if you like and inspect it, but that's really kind of odd.

Is the hall effect the same as the pickup coil? It sounds like that's a likely cause of the problem. When the pickup in my Lancer went bad, we put a spark tester on one of the plugs. The car would run perfectly for a while, then die. When I tried to start it again, there was absolutely no spark. As with yours, if I let the car sit for a while, spark returned and it fired right up. As slantsixness said, the pickup coil looking new only means that your dist. cap isn't leaking- there's no way to visually tell if it's bad. Plan on about $30-40 for a new one, or try one from a junkyard car (if it has the same year engine as yours).

Hall effect is the same as a "pickup coil", "distributor Pickup", "Ignition trigger", etc...

Ironman502,

Did you know that 6 out of 10 people believe they're not the other 9? So what does the other 2 fifths of the people believe?
Did you know that 2/5ths of the people agree with 4/10ths of the people, but not with the 3/5ths of the people who agree with 6/10ths of the people?

And, did you know that if only 1/3 of these people gave a SH!T, somebody could not have been whole?

:)

Haha! Nice. :iceslolan Brings to mind a quote by a famous football coach- I don't remember who- who told his players during a practice: "Ninety percent of the game is half mental."

Hard to imagine...
