VP replaceable sensors? which ones?

[discostuee]

Hi,
Im slowly getting to my tether before i rip out the engine and replace it.

Can someone tell me some sensors to replace, I have done the oxygen one already.
i know i dont need to do the temp sensor to dash.

but there is 2 more in the front of the manifold what are they? i think there is also one in the rear of the manifold too.

any sensor names / product codes so i an replace would be appreciated.

thanks
Stuee

The car's been running like a bag of pooh I think - Yes.

The sensors are ECU temp sensor (not the gauge one)

TPS on the throttle body and IAC valve.

There is problems, engine idling badly when warm, surging, when foot on throttle out of gear it it missing intermittently.
I have changed....

coil pack,
plugs
cables.
o2 sensor
map sensor
IAC
throttle body.
TPS
ECU
Relays
CAS.

now i think the only option is the temp sensors and any others in the engine (V6) that could be causing issues. Before i end up doing a rebuild. or push me to change to a VT v6 and auto earlier than planned (its in my toyota 4runner)

Was that list all new parts or one grabed from the wreckers?

The miss is most likely the coils DFI or CAS.

What memcal is it running? did you swap the memcal over into the replacement ECU?

have you tried the igniter, the plate the coils mount to and the loom plugs into
