ok im at my last straw with this car ive cleaned EVERYTHING new maf ect ect nothing makes a diffrence i have a egr code now my car falls on its face when i try to drive then wakes up and goes starting to get really annoying i have a baby so its really shi**y for him when it bucks like crazy

any help or advice would be gratefull

 

did you clean your egr tube? it's simple really. and most likely that's not the reason why your car stalls out. egr wil do anything to that affect. are you sure it's egr code? and do you have any other codes? more details are needed so we can help.

 

yes i cleaned the egr tube i had everything apart yesterday and it was running great then went to crap my code is p1400 but ive had this code since i bought the car my idle is around 750-800 has a maf from junkyard but my old 1 isnt bad i do have kinda crappy gas mileage im on a small budget so im trying to spend as little as possible

 

Sounds like what would happen if the throttle position sensor goes bad.
The computer would not know you pushed the gas pedal. So it falls on its face.


The cars that had carburetors had this symptom when the accelerator pump would not spray in extra fuel.


The surge would be the computer realizing that your foot is on the gas.
I imagine that when the car fall on its face, you would step on the gas. Then when the computer learns you did, the car will surge.

 

sounds possible do you know what i can do to test it ?

 

Drive with the throttle position sensor disconnected, see if it acts the same.

 

its runs and drives exactly the same plugged in or unplugged

 

change the fuel filter

can be clogged or the fuel pump has no pressure and accelerates when there is not enough fuel

 

..have you tried replacing the egr solenoid?

I'm getting the error for that as well and i need to replace. What happened one time for me was the car started bucking wildly after the error light came back on and i didnt know what was happening.

I pulled the car back in the garage and tried checking the codes with torque (code app on my phone) and it just ended up resetting the ecu.

It ran fine after that. I know the light is back now and the solenoid still needs replacing. Just havent been home to fix it. ...miss my car so much.

i dont think it looked like a difficult replacement. I know they are kind of pricey at the parts house - i was simply going to grab a couple at the yard and see which got the light to stay off.

When this happened to my 96 gle 4mt, I replaced TPS sensor and MAF sensor. Been driving normal since then

 

wow thanks guys im heading to the junk yard today

 

ok so i went to the junkyard and my car didnt act up at all on the way there ? idk but shes running alot better im gonna leave it for now what the power diffrence between the 3.0 and 3.5 ? how much of a pain is the swap and estimated cost to do the swap ?

 

I have p1400 too, car does the same thing, bought a used one on ebay. Ran fine for about 3 days, then same code popped up and car is back to doing the same thing.

 

If it is running exactly the same if the TPS is plugged in or not, the TPS most likely has a problem.
