soooooooooo....are you in the habit of interfering with sensors without knowing how to get them back to factory settings?
*sigh*
get a feeler gauge and a multitester
facing the engine with the TPS unplugged, the pins on the sensor from the firewall come forward are
VC
VTA
IDL
E2
take the feeler gauge and stick it between the throttle stop screw and the throttle lever (should be a squeeze to get at them between the intake plenum and the ITB's but it's your fault for interfering in the first place)
u should be getting these resistance readings for these clearances
0mm 0.3-6.3kΩ between VTA-E2
WOT 1.8-11.5kΩ between VTA-E2
0.8mm ≤0.5kΩ between IDL-E2
1.0mm ∞ between IDL-E2
- 3.5-6.5kΩ between VC-E2
for the AFM, there's usually a stamp somewhere on the top near the screw that should say 43 or 45 or whatever...this tells u how far from the top of the screw hole the screw head should be..it's usually in the neighbourhood of about 1.3-1.5mm
this is NOT an idle adjust screw BTW and should not be tampered with unless u know what you're doing...it is an Idle Air Bypass Screw and meters air past the vane on the AFM at idle to enrich/lean out the AFR at idle only
I dunno what to tell u about that hard start nuh.....when last u serviced your injectors?
any error codes BTW? |
