TK for the help i hope you can help me Tk Again.

 

inglese?

 

TPS adjustment could be needed from what i can comprehend. Type in complete sentences and use lowercase letters and correct grammar. English is good too. If you need help fast then type slower.

little better. do a search on how to adjust the throttle position sensor. Then get back to us on that. If that is within spec then check the timing, spark plugs, and all other stuff like that which could be causing a problem.

 

ok tk

 

If the check engine light is coming up, should he first be pulling codes before he spends time on anything else...

high idle is probably the throttle position sensor. the up and down is a vacuum leak.

 

Now in the manifol there is a part the electric section is connected but the air hose was socking air i blocked. is thad corect... if i take the EGR out wath are the concesquences ..

 

WHAT??? pics of the part your talking about would help.

and no egr you probably wolnt pass emissions, but other than that there are none that i can think of.

 

OK I mess with the timing now the RPM is over 2500. No more ups and down. But when i start the car runs fine for few seconds and starts to miss fire when i give to much gas.bump

 

oh wow CAPS IS REALLY ******* COOL

 

What is your problem.(idiot)

 

EGR was pretty useless, i dont know what you need to do exactly but its just for emissions

Learn to type brah, I don't want to read that first post

You need to pull the codes and check the tps is adjusted properly.

The tps is the throttle position sensor, it's alil black plunger with a few wires, you'll see it right there on the throttle body

 

OK Brah Tk for your knowledge.
