Hi !
Read several posts on the topic, but threads are almost never updated with what was the cause of your issue
So, 1989 GT. Stock engine. Used to run a Powerdyne SC, auto trans. ( originalky a manual car )
Mods was BBK shortys, 3:73 gears, 24lbh injectors with matching MAF. SCT eliminator chip and upgraded fuel pump. Car was working perfect, with or without the Powerdyne.
So i decided to go Trick Flow top end kit, stage 1 cam, Wedge heads and street burner intake.
I reused all the electronic stuff, same injectors, same MAF,same TPS, same IAC and i slapped the stock TB on for now.
Attached all vacum connection as pulled off.
So…first start up went fine, surged for 30 seconds the died. Managed to get it to idle ok…but runs like crap….dies if i push gas pedal down or it goes all sluggish on me.
TPS is at 0.97, timing 12 set without the spout connected.
I also swapped back to T5 manual by the way.
Removed chip, tripple checked vacum and timing.
It starts fine but wont run or idle at all. Throttle respons is beyond sluggish. It will idle fine reving it past 1500-2000 rpms.
Vacum is good 14-16 at idle even it doesnt idle….grest vacum at 2000 rpm.
Pig rich.
Smog pump and A/C is deleted. EGR is connected to dummy plug.
Pulled codes:
KOEO only 11
KOER
13 - Normal idle not within specified range
18 - SPOUT circuit open
21 - Coolant temperature sensor out of specified range
33 - Canister or EGR valve not operating properly
42 - Fuel mixture rich
44 -Air management system inoperative
65 - Fuel control system not switching to closed loop
92 -Fuel mixture rich, fuel pressure high
94 - Secondary air system inoperative
