If it sank to the bottom and stayed together, assuming it's liquid, it's water. Or at least, it's something aqueous

I wonder if that would be my problem. Its only less than a dozen drops out of an eye dropper. If that helps

I am starting to get a laundry list of stuff done to my car. Does that make it fast? No! Does that mean i spent too much money on a toy? Maybe. Do i have fun every time i jump in my car and drive? Hell yes.

Water will certainly make things interesting. Assuming it isn't from the container

How much gas is in the tank? If not much you could just drain the tank and put new gas in it after the pump to rule out fuel contamination. It seems like you have been having issues for a period of time though. I doubt it's the problem, but I have been wrong before

Did your afpr come with a gauge or did you get one for it?

Came with a gauge. I have ran the tank within a gallon left and pit gas in it like 3 or 4 time since the problem. I got about half a tank in there now... there was a slight miss in the idle for the last 15k but now stuttering and honestly it was that noticible unless you were holding steady at say 40mph in 3rd at about 3250rpms....

I am starting to get a laundry list of stuff done to my car. Does that make it fast? No! Does that mean i spent too much money on a toy? Maybe. Do i have fun every time i jump in my car and drive? Hell yes.

I also meant to say a few posts ago that i installed a new fuel filter not a pump. I also swapped to another stock fpr and purge valve as those are two things that the wsm said it could be.

I may drive it tomorrow since I have the pump in my possession now. I also replaced the vacuum line going from the IAC valve to the side of the intake manifold which bypasses the egr valve I deleted. They may have been leaking a little bit so i went with a soft rubber line instead of the stock one that was brittle and stuck into the shape of the vacuum line.

We'll see how this works tomorrow. I was supposed to receive the afpr today not the pump but i cant install it so whatever.

So my fuel pressure is at 40 -38 psi... I installed the pressure gauge from the tester between the rail and the fuel filter on the send side.... It's "dead" on so. I did not check it with the vacuum line off of the regulator. I think i may drive it for a little bit and see if i still have any issues. so am i looking at something other than a pump? I ran it for about 2 minutes i even revved the engine a bit and there was almost no rise in the pressure, by almost i mean it may have moved 1 psi.

There should be a slight fluctuation when you rev the engine, it should actually drop a few psi momentarily and then raise back to spec psi. I wouldn't worry about pressure with the vacuum hose off the regulator, if the psi is correct the regulator is doing it's job. I doubt it is a fuel pump related problem. However if the gauge your using is part of the afpr you ordered, you could pop the hood the next time it acts up and check your fuel pressure and report back.

The problem is still occuring I borrowed a tester from autozone and checked it in thier parking lot.

So drove it today hoping it would be better. No go. Didnt die but still had trouble holding idle. Then in third gear at about 2k rpm the car started surging a bit so dropped it into second at about 3k and it still surged but not as bad. Im starting to think its a ignition contolrol module or the iac is acting up from too much vacuum since I deleted the egr from the vacuum sequence. I may try the hei mod after I replace my cap and rotor and my fuel rail to make sure its not a leaky injector.

On the bright side when I figure this out my car may be running tip top for a long time with all the replacements and modifications.

Electrical issues often present themselves more so when the components involved are hot. Ie. When the engine has warmed in tge case of the ign. Module. You may be onto something here. The coil can present similar issues, but more commonly misfires under load or heavy throttle. If you do the HEI mod, there are some good posts on how to do it with an ext coil. I recommend it. If you need more help with it, drop me a PM

If everything was sealed up properly after the EGR delete I really doubt it's the issue. You won't have "to much" vacuum from removing it. Rhaski is correct though, when electrical conductors (wires, terminals, etc.) become hotter their resistance increases. A failing electrical component will exhibit more problems hot than cool. Another way to check for a leaking injector would be to hook up a pressure tester again and see how long the fuel system holds pressure. You shouldn't see more than a 10lb drop, preferably less, within 30mins.

I looked again at the manual and it says fuel line pressure should be between 37 and 42 psi. I was at 38/39 but it woild drop when I revved to 38. It wouldn't be hard to believe that it would drop under a load.

That being said I also swapped the injectors. Here is what mine looked likeHelp me trouble shoot my problem-uploadfromtaptalk1357703630192.jpg
I put the the other set in that was cleaner and the o rings looked newer if not new.

Another thing I was told to check was the temp/fan sensors on the side of the head that are by the valve cover breather... when I unplugged the rear one the idle jumped up aboit 150 rpm and the. Front one about 500 rpm and the fan kicked on. Both threw a cel so id assume those werent the problem.

Installed a new cap and rotor and bought the stuff for an hei mod. Hopefully I don't have to drop the tank. The only bolts on my exhaust are directly behind the flex pipe and im damn sure the hanger on the muffler have washer welded on to keep them from slipping. So getting the tank down is gonna be a bitch.

But heo mod is next then tps and iac. Luckily I have extras of both.

I am starting to get a laundry list of stuff done to my car. Does that make it fast? No! Does that mean i spent too much money on a toy? Maybe. Do i have fun every time i jump in my car and drive? Hell yes.

Its running much better. Held a pretty consitent idle the whole way to school and didnt stutter the whole way. Gonna drive it home and hope thet the next 10miles hold the same. Whether it was the injectors, the seals, or the cap and rotor it seems to be running better. Even seem to have picked up a little power. Now on to timing and resetting the idle. Calibrating if you will

For the record I just pulled my codes.

08 MAF/VAF
09 ECT (Engine Coolant Temp Sensor)
10 IAT
01 IDM/CKP (Ignition Diagnostic Monitor or Crankshaft Position Sensor)
69 Coolant Fan Temp Sesor


I can explain 4 out of 5.
The IAT and MAF probably happened when i forgot to tighten my throttle body boot and it fell off while driving.

The ECT and Coolant fan temp sensor probably happened when I was told to pull the plugs off of these sensors to check for a change in idle to see if this was one of my problems. It increased idle and the fan kicked on. I figured when it threw a CEL they worked!

the tricky one is this IDM/CPK and this is the one I think that mat have exlained my symptoms. I'm gonna look up possible causes and post back.

Well if it runs it isn't your ignition cas, it could be your cas by the harmonic balancer causing issues though. That would make it run like crap. It also is more likely to cause issues when hot, being an inductor
