Cadence

Ok i searched and found other people with this code, but no one with the same problem im having. My car will Hesitate and Cut out Pretty Bad at times. when i first start it up and drive around its the worst almost undrivable. When it gets warm it doesn't do it as bad or as often and sometimes not at all. I checked my codes and it came up with boost/pressure sensor code 07. I have an HKS FCD installed. Would the FCD Be Conflicting? or is it a totally different problem. also my trailing coil pack mount, the alluminum thing that holds it to the fender gets really hot. But the leading coil pack is at normal temperatures. it will only run decent when it is completely warm for a few minutes.
Thanks for any help.

Things to check:
The FCD connections- bright shinny metal contact.
Grounds - shiny bright metal to metal contact. (especially the cheesy clip on the firewall)
Spark plugs - rotarys eat steel leading plugs, maybe go platinum.
TPS - pull the connector, clip a meter on the orange & green wire pins, work the plunger, meter should show a smooth sweep from ~0 to ~5k ohms.

I have brand new sparkplugs in, less than a week old. the hks FCD is wired in at the ecu ill double check my connections. i just adjusted my tps a couple weeks ago, but ill double check that. Also i guess you can tell from the code but i have An S4 but its also a Turbo II.

The TPS Idle setting could be perfect, but as the TPS wears, it can give non-linear or inconsistent signals to the ECU.
A worn out TPS may give 1K ohms at idle, but have a drop out or short further up the scale.
A drop out at mid scale will tell the ECU to idle at that point & give a fuel cut hesitation.

ill check that thanks.
