Serious bucking and stalling
Posted: May 8th, 2010, 5:01 am
ZE swapped, no issues before I did this:
Got fuel injectors cleaned and tested (came back good)
Deleted EGR
Changed drive shafts
Now when I accelerate it bucks badly and I can see the RPMS shoot up and down wildly whilst doing so. I tried adjusting the TPS, it's not that. It stalls too after I try and take off. There's no air leaks, no vacuum problems. The VAF was fine before and I can't see it being crap now. Nothing is disconnected. I'm using a known good disty.
Idling, it's perfect. No signs of failure, it's only when I try and drive with some load, I can rev the engine's a-- of whilst idling with no issues at all. It's just when I take off I have issues and it seems to be prone to stalling after take off.
I actually put the fuel hoses on the wrong way when I reinstalled everything and tried to start with no effect. I dunno if this could have stuffed anything up. There really was not too much pressure coming out of the fuel lines when I took them off and tried cranking. Also, I do have a new fuel filter.
Not sure if my fuel pump is on it's way out.
