I have 95 probe SE-4 cylinder. Experiencing a loss of power with hesitation especially when attempting to accelerate. Also burning more fuel than usual. Recently changed catalytic converter-that was clogged but problem still exist. HELP!
Is your check engine light on? If so have someone run a diagnostic scan to try and pinpoint the culprit. This could be caused by any number of ignition/emission/ or fuel system problems such as filters, sensors,plugs,etc. If I had to guess than I'd check the EGR valve system and possibly the O2 sensors. A "clogged" catalytic converter would suggest this. Did you notice a rotten egg like smell from the car. Converters usually rust away these days...

the bigger tyres the more power it takes to turn them
You have very big tyres so suffer a loss of power
with extra power and the oil pressure falling, I would suspect worn big ends and main bearings especially with the smoking exhaust as under load of acceleration the extra clearance in the bearings is allowing extra oil onto the cylinders and the oil rings cannot cope.
exhaust system has no effect
There is a vacuum advance attached to the distributor. Inside the vacuum advance is a rubber diaphragm that can crack from age an no longer work. Sometimes the vacuum hose that attaches to it may not be getting proper vacuum. This device adjusts your timing when you accelerate. Improper function could cause the problems you describe. Also, a vacuum leak in any of your vacuum system could cause the problem your describing. Too much air intake on take off from a faulty vacuum system could throw off your air fuel mixture on acceleration causing hesitation until the air fuel mixture can catch up which is when the power comes back. Hope this helps.
DTC 0304 indicates a misfire detected in cylinder 4. Probable causes:
1. Control unit software needs updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system problem. Check ignition module, coil, spark plugs, and wires
5. Fuel system problem
Not sure what you mean by loss of power. If you mean lack of acceleration or bogging down, than a bad cat convertor can cause this problem because you are lossing vacuum during acceleration causing the vents to switch from floor to defrost. Hope this helps leave comment.
I have a 1993 Taurus GL V6 3.0L..I"am experiencing a loss of power. Hesitates on acceleration Only when It's cold.When is get hot it runs very good. I have Replace Spark Plugs Cap & rotor were change air filter & fuel filter & TPS/EGR..... & it has a rebuilt ENG in it...this could be a sensor. But which one could it Be?
Loss of acceleration, the backpressure noise and such are kinda tell tale signs of that converter having problems, feel the exhaust out of the tailpipe it will be warm normally have someone step on the gas and if its super hot it'd be a step in the right direction.
