the problem that i find is the o2 sensor have slow responce.goes from open to close loop but the ecu dont use it at the time done read it as active.when i start the car goes ok. if i turn off the car and start again have very little unstable idle and lose power. after a while when the 02 is activate...

check all the vacuum hoses to fit well and tight.not only from the oil trap to the ecu but also behing from the inlet manifold.use the diagnostic cable as the g259fsg told you.you will have a clear image to idetify whats goes wrong.where you find the tps?

i replace all the vacuum hoses and tight them.mine dont go to the divert valve but to the carbon canister.the spi mini have the connection that you told me.i try to find where is the spot after the divert valve to connect it. do you know where is?the servo work ok, but when i push the brake at iddle...

i cant find that spot.can you tell me where is exactly?the inlet manifold have 2 vacuum hoses.one goes to the oil trap in the air filter and then to the ecu. the other goes to the carbon canister.is that the reason for the increaae kpa and the unstable idle?or something else to fix it?

all the sensors are ok. the temperature increase normal. i use the rover mems app.the csv measurements seems ok.when start works ok after a while the idle is unstable.when begin to drive have missfires and then works perfect.when i slow down the rpm remain at 1500 1600 for a while and then goes to 9...

the kpa its between 36-44.the car looses power or run ok radomly.i didnt find something strange at csv file.can i find if the ecu have problem with the mems cable?

Hi to everyone, i have a rover 214 spi 1991. when the car its cold the idle works nornaly,after a while when begin to warm the idle is unstable.i check the fuel filter new,vacuum leaks,pump pressure,relay,all sensors work ok it checked with mems plug and with multimeter.i change spring to the brush ...
