i searched the forums to see if i could figure out why my 1988 turbo II was only running on one rotor and found that it could be a bad fuel press reg, a Leakey injector or a blown coolant seal.

my car would only run on one rotor at start up once it got wormed up it would smooth out and run fine.

i had a rtek 1.8 that i bought here on the forums 2 years a go so i got 4 720cc injectors and a new fpr and installed them. now it is running very bad all the time.

i noticed on the rtek ecu that the number was different from mine. mine said n333 and the rtek was n332. is this a problem? it was sold as an s4 rtek and all the ecu plug-ins were the same.
the 720cc injectors were bought on ebay from tlf performance parts, he cleans and flow test them and gives a 1 year warranty so i would like to think they are good

it never really smoked much so i did not think i had a bad coolant seal. the first test drive it did get rather hot, temp gauge went up but not all the way up to the H. but it looks like it may be a bad radiator cap.

second test drive it did not get hot, no smoke, but i did notice it has a boost leak (which i do not think would cause it to run ruff) but as i turnned back into my subdivision is when it started running extra bad all the time, was running smooth before.

any ideas will be helpfull
thanks

 

did a compression test, have 100psi in both rotors. all looks good there

 

Wet plugs and possible TPS issues might cause this problem as well as a faulty ignition.

 

all 6 faces, right? sounds good

 

all 6 were good. will check the tps, plugs looked good but i could clean them to be sure

 

bad injector connectors.

 

i tested the injectors and they are working.

but i saw coolant under the car, it looks like it is leaking from the turbo. it is coming out of the wastegate lever on the hot side.

could this be causing it to run ruff? i do not know how the turbo is put together (my first turbo car). but could the coolant be getting in the compressor and sent into the rotors?
