Check your rotor under your distributor cap if you have one. That should be replace. Also did you check your mass air flow sensor. you can buy a special spray to clean it out. Do you have a throttle body, if so it is so easy to pull and clean it out. Check your throtle body sensor.

there are a lot of auto part stores and garages that will do free computer checks now. Take advantage of this.

your definately on the right path, just keep digging. Also does your car have a turbo, this could be your problem.

A couple of thing's right off that it could be is a plugged catalytic converter , plugged fuel filter or a weak fuel pump. Are there any lights lite on the dash , check engine light etc.. Have you experienced any strange noises or happenings ,like engine back firing. How does the engine run ,smooth ,ruff ? Have you had spark plugs changed and wires if it has them ?

What would cause lack of pulling power?

check ignition timing, exhaust system for blockages, fuel pressure ,injector tip condition, blocked air filter. Run the fault codes to check for faulty sensors.

99 sc1 overheats and lacks power

sounds like the catalytic converter is pluggged, not allowing exhaust to escape, therefore causing the engine to be hotter on topside, and loss of power

Ford code p1152

P1151---Lack of HO2S-12 Switch (lean)

P1152--Lack of HO2S-12 Switch (rich)

Just replace both front O2 Sensors,the ones
closest to the engine--assuming they have
100,000 miles on them

Rock Auto.Com --best prices on quality parts

You should check the writing stamped on the
current sensors,they may be Bosch,but ford uses
NGK/NTK also

You will find the new ones will have longer wires
& may have different color plastic connectors
Not a problem,just curl up the wire,plug in & wire tie
away from exhaust pipes

Your code was only one side, do both,not the rear
sensors at the converter outlet,they stay almost
for ever

My 95 volvo is running rough after i changed the fuel filter!!

Sounds to me like simple plugs and wires if that isn't the problem I'd then do your cap and rotar! And possibly timing but go with new plugs and wires and be sure to gap them right is under the hood you'll ding the sticker

Iv have a 91 chevy s10 w/2.5 5spd it stalls on highway(not cool)sometimes it will restart sometimes it wont.iv replaced the batt, fuel pump,regulater,relay,filter,sending unit,pickup coil,ing mod,...

Now that you've replaced nearly everything, the only thing left that I can think of is the oil pressure sending unit. If this is bad, the fuel pump shuts down, possibly causing the problem. However, before buying a new part, find the wire for the sender and ground it by attaching it to something on the engine. You won't indicate any oil pressure, but if this IS the problem, you'll know quickly. THEN go buy a new sending unit.

The samurai tranny shifter's wear down and the shift pin tends to break cause slop in the shifter and making it harder to get into 5th gear.
