the idle is stuck at 4000 RPPPM ... anyone know what it could be ?

 

stuck throttle plates, throttle cable not properly adjusted, and vacuum leaks.

 

i checked the throttle cable and plates ...... im gonna go with a vaccum leak too...... also how long did it take you to throw yours in and get it running right ?

 

the day i turned the key really. but i found out my pressure sensor was plugged and i was running like 15psi and my clutch slipped. so i needed a new clutch and Presusre plate.

 

it took me 3 days to swap everything in and out ..... it was really an experience though ....... im half dead lol

 

you kow your car inside and out eh? best feeling ever.

 

i would say ... but some problems i cannot figure out ..... but i love the sound of the TURBO ...... man its nice ... i have never had one before

 

good to hear you like it, how much did this run you if you don't mind me asking?

 

i am doing a 88 n/a to a 91 now that is geting to know your car in and out but i have to thank dan atkins for his help

 

give me a ride in it sometime sucka! never been in a T2!!!!!

 

i payed 800 for the motor ... 130 for ECU and 25 for Pressure sensor. i payed 70 for the AFM. i payed 100 for the tranny and i have a limited slip custom N/A diff ..... came in car when i bought it. i have an ACT clutch 200 and i got a free driveshaft.....1225 i believe it works out too..... so its not bad ..... how much did you pay for yours ? if you dont mind

 

about 3k-4k, but i bought the diff drive shaft and such, 1000 for motor, 150ish for the rtek ecu, 260 for electronics. sitting at 500ish fo the 5 bolt conversion, that has to be installed. 200 for exhaust, 100 on paint. 520 for the act clutch. rest is misc. crap.

 

Congrats!

 

sweetness ... alrighty thanks alot guys . Once again you have helped me out of a jam.

 

Impressive, well done and looking forward to see it.

 

With regards to the original problem, the size of the vac leak required for the car to idle at 4000 rpm would cause it to not idle in the first place.

Like Nismo_convert said, throttle plates or cable is probably the issue. Also, make sure your intake plumbing is correct as well(there are no air hoses bypassing the throttle plates).

 

idle now surges between 1200 rpm and 1800 rpm .... Any ideas ..... no vac leaks.

 

tps, but you know you need one

 

i checked it out ... no dead spos and i set it right to 1.000 and doesnt get past 6.000 ..... i guess it could still be bad i guess ..... this is really stressing me out .... i just want to boost hard and be happy with a proper running car.

Also could it be the throttle plates ?

 

throttle plates would create a high idle not a fluctuating one.

 

ill try the damn TPS ...... thanks again

 

if you have verified that the TPS "sweeps" correctly and then set it to the proper resistance, but you STILL think it's the TPS, then use the Mazda 2-light test method.
