Why does my Ford Ranger have a low rough idle?
The truck was idleling smooth and drove fine. The truck always started right up. A day maybe two after changing the plugs, I started noticing the low rough idle. As well the battery gauge would fluctuate up and down (maybe a 1/4″ of movement). However, as long as I was driving or giving it gas everything was stable.
Is the oil gauge out on a Ford Ranger?
Also, the oil gauge will flicker like crazy occasionally at idle. The door sensor is out also if that matters. When I bought it, it idled rough, but at the appropriate rpms (650-750 in drive) but it was missing.
Where are the spark wires on a Ford Ranger?
One thing I saw was a snipped small red (apprears to be a ground) wire just left of the fuse box bolted down under a wierd plastic can lookin thing (zero idea what it is). I will post a picture later today. I thought I would start with the basics, clean the MAF, IAC, replace the PCV. change my spark wires as well.
How much does it cost to replace low rough idle?
Re: LOW ROUGH IDLE, Sometimes dies! Costs around 50 to 60 bucks and takes about 5 minutes to replace. You can try cleaning it out but I would recommend replacing it. Its on the air intake right at the top of the motor. It has two bolts holding it on. I just replaced mine on my 07 3.0 with only 38k miles on it.
Why does my Ford Ranger run for a little then dies?
Next check is the fuel pressure regulator, your looking for fuel coming out the top and bleeding into the vacuum line thus flooding the engine. Another thing that happens is the distributor pickup coil can fracture, it runs good until it gets hot then it will go open and the engine stalls, and the ignition module can act the same way.
Can a Ford Ranger run with low fuel pressure?
So check the lift pump first if it is running and pumping a good stream of fuel then move onto the pressure pump, and yes your fuel pressure is low. Here is a chart. All makes and models. http://jameshalderman.com/links/book_adv_eng_perf_5/s_and_c/F uel_Pressure_Specifications.pdf
Is the Ford Ranger 4.0 EFI distributor?
Joshua this truck does not have a distributor, but I found the problem. It’s a 2000 Ranger 4.0 EFI and they replaced the original coil pack and the thermostat, that was sticking, and so far has cured the problem. Thanks for the help. 2 people found this helpful.
What causes a spark on a Ford Ranger?
That will only check the coil output, if you don’t have a trigger signal from the ICM then the coil wont fire. The distributor pick up generates the magnetic pluse that the ICM reads and generates a trigger signal and sends that to the ignition coil and in turn if it has stable incoming voltage fires a spark. 7 people found this helpful.
