New to any forum but looking for answers, replaced egr and solanoid, car still missing wen it comes up to temp checked valve befor replacing and it faild on vac test I seem to have good vac coming in from the hose no leeks and such . I only get the missing when van is up to temp hope its not PCM

 

Is P0401 the only code you are getting? Are you getting any misfire codes?

 

must have duplicate threads, you take this one, MT and I'll take the other....lol

 

no miss fire codes although I cleared the p0401 code yesterday with the help from a tech I work with and he he isolated each injector thay seem good he thinks coil plugs or wires why does it not give me miss fire codes he said not all cars will give me a miss fire its been 70000 miles since i did a tun up , but again it only runs rough when i get up to temp 10 15 minuts ill look at plugs woork my way back, what do you think

 

Did the ck engine lite come back on? If it did what is the code. An EGR problem will cause some driveability problems.
