Ok, the coolant leak problem is no more, found that it was on the turbos with 3 vacuum leaks, sucking up the coolant from the leak, odd as it may seem.... that problem is over with.



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?

if its doing it at a steady speed, it might be the o2 sensor

I'm running a PowerFC, i check the connectors on the harness and the ECU...



I checked all the grounds, they are fine...



I always seem to have the weirdest problems...



The car is VR..lol



If you want i can list every mod i have, but i'm afraid it would take a long time... maybe it would help?

we had one where when it got warm it would intermittantly die, it turned out that the crank angle sensor wires were bad somwhere in the harness

i have voltage to the crank angle sensors, beginning to think the my primaries are plugged or something...

its possible, i'm trying to think of something stupid it could be though
