Having a problem with the car...


I drive the car around for the day and it runs perfectly.
I park the car, and the next morning i go to class, and once in a while the car will buck...
I park the car at school, go to class, come back, and on the way home the bucking has become more frequent and more violent... plus now everytime i try and get into boost the car will back down and buck...

I park the car at home, i check the MAP sensor and the TPS sensor voltage on the PFC, both are fine, both are fuctioning and are connected.

So now i have a friend come over and we are gonna see what the problem is, but now the car bucks ALL THE TIME and its impossible to drive.

I park the car, can't seem to find the problem, it feels like fuel cut, so i'm beginning to wonder if one or both of my primary injectors has failed.

Car has 98,000miles on it, but brand new engine. The car will not start now, the car has new plugs and wires, and voltage to the coil packs. Am i just not getting any fuel now? The pump is running...

Any Thoughts?

 

Check your grounds. Since you have a new motor one may have been neglected or have gotten dirty.

 

found it, fixed it...

3 vaccum leaks and a coolant leak above the turbos, vaccum leaks were sucking in the coolant leak...

 

Can you PM me with the details of the vac's that were bad haha as if it going to help me but I have the same exact problem! Btw I PMed you

 

Did you use vinyl caps the first time? If so, don't.

 

oh the other problem was with my fuel pump. The metal "hook" wasnt bent up so the pump was kinda detached from the fuel lines..so it wasn't pumping fuel correctly.. that was one.. man this thread is old heh.
