Car bogs when A/C on

[talon_boy69]

well...I'm trying to figure out what's causing this...when I turb on the A/C the engine basically shuts down...sometimes it can get really low and then it compensates...but DAMN! I HATE THAT!...I'm trying to fugure out if it's the VPC or the ACT flywheel...I guess both, but I'm leaning towards more to the vpc...it seems that if I richen up the response it helps, but it's on 6 o clock!...I think I'm going back to maft!...Any how..the real question is for you guys with ACT or light weight flywheel or VPC..or both...do you have this problems???

Has it always done this or did it start after you installed a part.
I'm assuming(you didn't tell us) that you're talking about at idle or when you push your clutch in and the RPM's drop.
If I'm correct, read on.
What is your car's idle normally?
The part that compensates when you turn your AC on, at idle is the ISC
When you turn on the AC, it puts more drag on the engine. Idle drops. To compensate, the ISC opens up more and allows more air to bypass the TB plate, increasing idle(simple terms) and keeping it from stalling.
That's the easiest thing to check first:

Good luck

yeah, I know all that, thanks for the info...forgot to say, but this is only when I turn on the A/C (compresor clutch engages)...and is happening since I changed ACT flywheel and VPC...so one of both is causing this...probably both...I'll bet on the VPC

Just an idea, have you rewire the fuel pump yet?

 

[talon_boy69]

yes, it's rewired...BTW...I installed the 1g mas and problem solved ...I'm getting rid of the damn vpc...thanks for all guys
