Hey whats up ... i put this motor in my car ... soo it starts and idles but wen i give it more gas it boggs and dies.. i tried the AFM swap .. still did the same ?? can someone help me please ? ? thanks

 

^lol, dude...NEED MORE INFO!

Did you really think we could figure out what is wrong with your car with such little info?

 

Okay slow down, What year is the car? Is it a s4 or s5 ? Is it a n/a or turbo? what type of swap did you do? N/a --> N/a ? Pics or even a video would help too.

 

NA s4, I have been going back and forth with him on the phone. Did a straight NA to NA swap after his motor was dying. So far I told him to check the FPR, the vac lines, and airflow meter.

 

yea what Socal said .. sorry .... soo i check AFM , Vaccum ... still Boggs ... between 1500 it dies .

 

FPR as well ... still boggin

 

The wires to your spark plugs hooked where they are suppose to be? T1 T2 & L1 L2....

 

IM going to make sure ... back in 5 ..

 

soo i checkd and yea still the same....

 

SOo Does anyone have a CLue ?

 

Check CAS & TPS... dunno what else it could be. Is the idle steady, high, low, choppy, go up and down?...

 

well check it out ... i took off emissions capped off the stuff i dint need .. bac capped .. EGR capped...thermowax in the throttle ... when the car starts i gotta give it gas to stay on and i slowly drop the revs and idles at 750 .. steady .. but wen i give it gas to rev it boggs and dies .. soo yea

 

im almost there ...

 

check the TPS voltage and resistances. should sweep steady from 1k ohms to 4.3-4.6k ohms or 1 volt to ~4.5 volts as you apply throttle, no dips or spikes while applying it slowly.

 

hey thanks .. karack ... im check the tps ... hey karack i wanted to throw in that i swapped my primary injectors...you think one of those injectors i swapped aren't squirting ? ? i mean wen i start the car i kinda gotta give it gas to get it to go then i slowly decrease the revs to 750rpm...i called lucky seven they said some electrical prob... imma try the TPS first .. Anyone got a voltmeter ? ?

 

could be an injector issue, the injector plugs do have plenty of problems with cracking and pushing the pins back into the connector when you plug them in, the coolant temp sensor on the back of the water pump has the same issue and can cause similar issues.

 

im gonna swap out the injectors i swapped in ...as well .. i dint know the condition of the injectors i swapped in ..soo maybe thats the prob. . but yea thanks for your help ..
