so i just droped in a Z6 in a 90 dx it went in good no problems but now its not revin pass 2k sometime 2.5k...im THINKIN its either the MAP sensor or the TPS sensor thats ****ed up ...when i put my palm over the throttle body it idles normaly...as soon as i let it go it accelerates crazy and shuts off after bout a minute...i bin told its the dizzy or the wiring but it was runnin perfect when i had it boosted on my eg...the harness is from rywire and its all hooked up rite...i have no idea what it could be so if any of yall know or had this problem i would apreciate any help

 

Sounds like it is your MAP sensor but try switching the plugs for the TPS and the MAP around and see what happens.

 

ive tried that and the motor wont stay on it shuts off...2moro when i go to work im gona switch map sensors from a diff throttle body and if that dont help it then im switchin throttle bodies AND if that dont work then im stuck lol

 

Did you recently take of the Throttle Body? Sometimes people put them back on and use too much RTV and it plugs the hole for the map sensor. Either that or they put the gasket on wrong and block off the port for the map as well.

 

i took the stock throttle body off cause when i was takin the swap out the eg the tps sensor broke so i used a d15b7 throttle body but i had forgoten that it was doin the same problem on a diff engine so i got to thinkin and came to the conclusion that either the TPS MAP or the whole throttle body dont work so i got a good TPS sensor and put it on the stock Z6 TB that was workin fine before...i didnt use any RTV cause the TB gasket was still on and it didnt rip so i didnt figure i would need to replace it

 

I would double check that throttle body. Also did you set the TPS correctly? That could be some of the problem too if it is not seeing enough voltage to make it REV any higher.

 

ok about the TPS you kno how is got them weird screws well after i got it out by cuttin it with a saw disc thangs i but reg screws BUT made sure that they fit without any leaks now i coulda messed up and mayb thers a leak i dnt kno if that would be a problem but as far as puttin the TPS on rite with the lil stick thang between the other 2 lol it was on rite...i hope u kno what im talkin bout lol

 

a would a DOHC zc throttle body fit on the Z6? it should since its all d series basicaly cause i got a unmolested zc and ill take that throttle body off it and use it

 

??? Your English is poor, sorry. You need to set the voltage for the TPS. It is not about just putting it on there and having it bolted down. There is actually a specific voltage that the ECU needs to see other wise it will think you have more or less throttle pressed down.

 

lol its cool i just dont like typing with good grammer but how do i check to see if the voltage is right or set it? im runnin a chipped p28 and i have another virgin p28 that i havent tried yet

 

Dr. Charles Madrid of Skunk2 shows you how to set your TPS about half way through the VID.
