Today I left my 04 idling for 15 mins or so and when I took off the turbo would spool up, but it took almost 30 seconds before the truck had the normal amount of power. After about a half hour of this, it came back and is now running fine, just a clog or should I be worried about more? In the previous days, if you get into the throttle and make it downshift at around 40 MPH, when it gets into a lower gear the turbo would spool too high and sound like it would spool down and back up causing the truck to jump.

 

Any smoke? My first thoughts would be stuck egr valve. After that check for codes, if it is the turbo and it needs cleaning should set a code, also do you have a boost gauge in it?

 

First off welcome to FTE

Do you have any gauges???

How about got the codes read


it may have some even without a Light on

 

No i do not have any boost gauges but I looked for smoke and there was none. No codes either, should I have it looked at on a computer though?

 

Start thinking about a ScanGaugeII theres a few things to watch out for

there 160.00 from autozone or www.scangauge.com

it will show alot of sensors

AE is another option its a computer program you put on personal PC its the Best thing for an owner to have especialy for injector issues

with the SGII you can pretty well watch all engine sensors and check there values to see if somethings off LOTS of guys run these you maybe able to catch the problem with SGII

but without something to monitor with you cant really see whats going on and you would just be changing parts what can get expensive

Another option would be to have FORD run a diagnostic IIRC 100.00-150.00
