SOURCE: bad stumble on acceleration pops through t- body.

Sounds like the fuel pressure regulator. Could also be that the timing jumped. But I'm leaning towards the pressure regulator. Hope that I could help. Best wishes.

SOURCE: engine runs rough at certain speeds 3.0 v6 flex-fuel 1999 ranger

Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..

SOURCE: Starts fine, but then bogs out when accelerating,

Check the fuel pressure regulator and the EGR valve, I would check the fuel pressure regulator first and go from there. Good luck and keep me posted. Not sure what the pressure should be but thinking it's 62 to 65 PSI upon start up and should drop 5 PSI when engine running, check the vacuum line to the regulator.

Is it the engine vibrating or the car? If its the car itself it sounds like u need to have the tires checked & balanced.

This can be caused by a faulty throttle position sensor (TPS). It will normally be found on the end of the throttle shaft oposite the cable connection. They are fairly simple to replace, and cost less than $50.

2000 GMC Sonoma Vibrates at 25 and 45 mph


Generally, the tire vibration only arrives at 60ish.
However, if you have a distorted tire, or worse, more than one, or even worse, Buckled Wheels!
You are inevitably going to experience vibrations, at varying speeds.
Take the wheels off, and make sure, the wheels are actually still,, er, circular.
It's best to put them on a Balancing Machine, then you can see how bad they are.
If the problem isn't solved soon, you may well be finding yourself, forking out for new wheel bearings.
That should do it.
Happy motoring.

CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) monitors the difference between engine speed and transmission output speed. In D3 drive range with the TCC engaged, the engine speed should closely match the transmission output speed. In D4 drive range, with the TCC engaged, the TCC slip speed should be -20 to +60 RPM .

When the PCM detects excessive TCC slip when the TCC should be engaged, then DTC P1870 sets. DTC P1870 is a type B DTC.
