So it started while i was driving it ran smooth and came to 1 stop sign and took off then the next sign 2 block down the road and started bucking on me.
It seems to only idol ruff when in 1st gear and in park after 2nd gear it seems to smooth out. It keeps a consistent 23-25 Mpg.Its 3.3l. I replaced the EGR/IAC and TPS all codes that poped up when it started . I also replaced Spark plug/wires the only code its tossing now is error 17 which has to do with the van not heating up fast enough with in 5 min. I took out the thermostat to change it and didnt get it back in yet but the issue started before the thremo was removed. It does or seems to stop after like 20 miles of driving.
OOO yeah whats OEM for the 3.3l engine?

 

went threw the vacuum lines blew smoke nd only found the bend plastic line to the pcv valve has a leak.. im going to guess now its bad fuel injector on cylinder 5. Anyone have a good tutorial on how to rebuild them?

 

Coolant temp sensor? you got to start with fixing the codes, right?
