1995 max hesitation under pressure
ok so i have a 1995 max runs fine when cold once warmed up its idles alittle rough but when i start to drive it hesitates (stutters) not major if i get on the throttle it goes away but comes back once i baby it ? any ideas alot of people say coolant temp sens does that sound possible as its only when warm ? ive also heard IAC ? please help thanks also does have a CEL i dont know the codes yet

Because there are multiple things that can cause this, I would prefer to find out what the CEL code(s) are. Below is a video on how to get the codes.
The oil leak is most likely the valve cover gasket. It does have a tendency to leak.

A loose oil filter can cause a leak on the passenger side. Yesterday I completely discovered my oil loss issue. The oil filter had backed off enough to start leaking. I'm worried now about how long I may have been driving with lower oil pressure.
So as far as the oil leak goes, check you filter, if not that simply look around the motor and look for areas that are saturated with oil. Like Dennis said the valve cover is the usual source of oil loss.
Good luck with the performance issues, I've been trying to pinpoint my problem for a while now. In my case I'm pretty sure its a combo of things, the main one being coils and the bad filler neck

0505 means no problems are detected. You probably cleared them by accident trying to pull them. I'm guessing you have a misfire, coils are the cause most of the time. Is the maintenance up to date, plugs, filters etc?

OK we can rule leaking valve cover gasket out...here's a thought. You obviously changed the valve cover gaskets because they were leaking. Right? So if they were leaking before then oil could of gotten in and around the spark plug valleys and ruined the boots on the coil packs. Check the condition of those boots they should be good strong and flexable rubber with no cracks. If the boots are brittle or cracked they are no good and will leak spark. Have you checked your oil filter to make sure its snug? Other than valve cover gaskets, cam and crank position sensors, or loose oil filter, I'm not sure where oil would be coming from on that side. Maybe the oil pan itself?

Code 1103 has to do with the transmission apparently...
" 1103 1104 1105 1106 Since DTCs 1103 to 1106 deal with the transmission, there is info on the 1106 DTC. Everywhere you see "4th gear", simply substitute "1st gear".
Diagnostic Trouble Code 1106 means "Automatic Transmission 4th gear malfunction."
This malfunction is detected when the automatic transmission does not shift into fourth gear or the torque converter clutch does not lock up as instructed by the Transmission Control Unit. The factory service manual lists these possible causes...
- Shift solenoid A - Shift solenoid B - Overrun clutch solenoid valve - Line pressure solenoid valve - Each clutch - Hydraulic control circuit - Torque converter clutch solenoid valve
You can do some troubleshooting without opening the automatic transmission. Find the harnesses which emanate from the transaxle. One of them terminates in a brown plastic connector with eight pins. This is connector F42, located (approximately) above the transaxle case and below the black plastic engine air intake ductwork. With the engine off, disconnect F42. You want to measure the transmission side of F42. Hold the connector such that the plastic latch is at the top. You should now see two rows of four terminals. These are numbered (top row, left to right) 1 - 4, and (bottom row, left to right) 5 - 8. Make resistance measurements between a clean ground and the following terminals:
#1, Shift solenoid B, 20 - 40 ohms. #2, Shift solenoid A, 20 - 40 ohms. #3, Overrun clutch solenoid valve, 20 - 40 ohms. #4, Line pressure solenoid valve, 2.5 - 5 ohms. #5, Torque converter clutch solenoid valve, 10 - 20 ohms.
There is also a "bench test" procedure for testing these solenoids with a 12 volt supply such as a car battery. However, this requires removal of the shift solenoid valve assembly. I don't know if you want to get involved with that."
1005 has to do with the egr..
" 1005 1005 is EGRC Solenoid valve
The majority of my information about Diagnostic Trouble Codes comes from my '99 Maxima factory service manual. Unfortunately, DTC 1005 is not in that book. Starting in '99 the Maxima engine uses a step-motor type of EGR valve and with that change, the DTCs changed. The Chilton and Haynes manuals provide a little information about the EGR Solenoid Valve. The test procedure for this part is found in the Chilton repair manual (page 4-11) and the Haynes repair manual (page 6-20). Test the valve and replace if necessary.
This malfunction is not an emergency but should be resolved fairly soon (7-10 days). An inoperative EGR valve may result in engine pinging and a variety of driveability complaints."
I found the above quotes in the stickies.

I have down loaded the IDX, EL and EC sections for the different years as most inquiries will use these sections. Having these on my hard drive is faster than internet access.
