Bog at 1800 rpm's

[xxShaneOmac]

When Im driving at 1800 rpms my car just bogs, More gas at this area is just a harder bog where i feel all my power cut and my car just shakes kind of. When its cold and not warmed up it does it 100x worse.

And when im really really warm i bearly notice it.

Its only at 1800 rpms, no matter what gear or what speed. 1800 rpms does it.

Mods-
Dsmlink

fmic shorte route
1g bov

i dont know what else would be along the lines with this problem

started to happen after hte injector / fuel pump install.

Theres probably more to it than this, but it sounds completely normal to me. It's a 2.0L engine hauling around a 3400lbs car. We make 80hp or something silly low at that rpm range.

change the coil pack, mine was doing the same thing i replace the coil pack and the problem went away

Who tuned the link?
Whats your afpr set at?
I think you are running lean maybe.
Could be time for a full tune-up.

Well, My AFPR is ~43 w/o vac hose.
I notice w/ the vac hose its appx 39 and when i rev it goes up to mid 40's, thats with the hose. but im not sure what that means.

My o2 wideband is reading a horrid 11 when i turn on my car but it dies down to 14.5 - 15.7 at idle and normal cruising.

Horribly rich at wot 10.0

The link isnt tuned yet, but i was under the impression all my tables and vaules are only under effect if im 100% wot, so this shouldnt matter when driving around..

And I may be in for a tune up.
What would this entail in your guys eyes for our cars.

Horibly rich at wot?I think that puts your link in effect rite there.
You regulater jumping with the hose hooked up is because like all vacume hoses they pull harder in higher rmp's

I would highley recomend you get the link tuned and do a FULL tune up.

The afpr should be 43.5 at idle without the hose attached, so that is right. But with the hose off, the afpr should not be 39, it should be less than that. However much vacuum you're boost gauge reads at idle, thats how much your fuel pressure should go down when you attach the hose. How much vacuum are you reading? The afpr is a 1:1, this means that the fuel pressure increases 1 psi for every 1 psi of boost/vacuum you see, that's why the afpr goes up when you rev the engine. For example, at 15 psi of boost, you should have 58.5 psi for fuel pressure.

What Would a FULL tune up consist of

could someone make me a list please.
thanks.

 

[pitbull419]

Plugs,wires,oil,oil filter,air filter,have your coil pack checked(replace if needed)have your resistor pack checked(replace if needed) egr valve(might as well block it off)
Check for boost/vacume leaks.Injector leaks,exhaust leaks.

TUNE YOUR dsm limk

How would i go about testing my coil pack and resistor packs?
and if they are bad where can i pick up new ones?

what spark plug / wires would you recommend for my car with the basic mods i posted.
run 14 psi dd
18 w/ the controller turned on
and gona get it to low 20ish on a tune im guessing.
