Question edited for a lot more clarity. 'lose' and 'loose' are two different words and your space bar appears to be broken. :>D
So it seems the car is running on the fumes of the throttle body cleaner, yes? Did you disconnect the battery when you changed the fuel pump? Did you reset the ant-theft and immobilizer?
If the throttle body is the issue, remove it and clean it properly both sides so it opens and closes easily..
The electronic throttle actuator (throttle body) can fail causing a loss of power ... start it studders like it is running on 2 cyl. then switches to 3 cyl. then to 4. but ... Throttle body replaced on my 2006 Nissan Sentra 1.8 engine. ... I Was going up a hill and I tried to speed up, all of a sudden my car bogs down and completely dies.
If you have a cable throttle then not likely, if you look at your throttle body and it is electronic then it could be the throttle body position sensor or possibly the accelerator pedal sensor. Are the any DTC codes present on your truck (check engine lights) cause both of these issues have sensors the will most likely trigger a code light on the dash. If not light comes on I would have it scanned just to make sure it doesn't have any codes stored in memory
This is a common problem with GM's. The TPS sensor goes bad in the throttle body. Throws out a message to service Stabilitrac. Not SO!!!
The kicker is that the whole throttle body has to be replaced because the TPS sensor is actually part of the throttle body!!! Costs around $250.00 for aftermarket.
If it is bad? I don't think it go's bad. It will break then it wont start. When you try to start it the engine turns over very fast. If it jumps a tooth on timing then it will spit and sputter. Backfiring either in the throttle body or exaust. Or both.
im assuming the reduced power message comes on where the odometer is, try cleaning the throttle body with some throttle body spray cleaner.the carbon build up in the t.b.i. will cause false throttle position sensor readings .if indeed the reduced power warning is coming on and cleaning the t.b.i. does not rectify the problem, the throttle body may need to be replaced. approx. 100.00 at kragen,auto zone,ect
Sounds like the pipe/connection from the exhaust manifold to the EGR valve that is located at or near the throttle body has a leak. That would make a loud popping noise.
could be the idle air control solenoid , its right below the throttle position sensor(opposite where you can open the throttle with your hand) on the 3.3v6, when that goes it does all sorts of stuff, bottom line its going to have to be put on a dyno to see what it is but you can take that part off and get one at the junkyard we got a whole throttle body for 10.00. Try also to disconnect the electrical connector off the idle air control solenoid and see if runs any differently, then youll know right away
