YOU ARE THE MAN CRUISER!!! Only tip the PO didn't do was dizzy indexing. Set the dizzy properly and runs like a top. I want to thank you for your tips because I was going bat $#!& crazy.......once again, you are THE MAN!!!!!

Spoke with the PO, he said that he followed all of your tips to the T, including the intake gasket

Wouldn't that cause a other issues then just stumbling between 1500-2000 rpm though?

PO installed HO intake and exhaust manifold so there's only EGR

NGK BKR5EIX plugs TPS tested good Every gear and sitting in the driveway. Always between 1500-2000 rpm. Idles great as does when i snap the throttle, but slightly increase throttle and stumble at 1500rpm

Replaced plugs with proper .035 gap(po had them at .025) cap and rotor are in great shape. Doesn't seem to run as rich but still has a stumble about 1500 rpm til about 2000 rpm. My son will be home in about 3 weeks to drive this thing from Florida to Kentucky and I really need to get this thing running right but I am lost at this point.

Thats next. I didn't think it should be an issue since the PO put all new caps, plugs and wires on it before i got it. Hasn't hardly ran since he did it all.

I have it fired up and running, been over 29 minutes so it seems like a new coil and wire fixed that issue. It still has a bad stumble between 1500-2000 rpms which i can't figure out plus seems to be running rich.

Fuel pump ballast resistor has already been bypassed by the PO, along with all of your other tips

It now runs but besides the sputtering between 1500-2000 rpm, it will just shut off after running for 15-20 minutes. Hooked an actual fuel pressure gauge and it maintains steady pressure. It really seems to be ignition related i just can't figure out what exactly

I went through and unplughed every sensor and re connected them and it fires up and runs. No clue on which one it was but its running now. Still has a sputter between 1500-200 rpm though

CPS is a constant .7 AC volts when cranking so i guess i can rule that out?

I will do that when my wife gets home so she can crank while i test. If the cps is bad would it even start though?

I did do that and no change. Fuel pump runs and puts out great pressure. I am thinking it may be igition related. Just because the coil is new doesn't mean its any good.

I have to wait a while before it will start back up. So when i can get it started i will let you know.

No. It had the trouble before the new CPS. My wife wanted all new parts and sensors on it since my son will be 5 states away after he returns stateside.

Also, new alternator, fuel pump and fuel filter.

1990 MJ 4.0 with AX15 Original problem was it sputtered between 1500-2000 rpm. Tested and replaced bad MAP sensor and since i am trying to make this right for my son, i replaced the 02 sensor, coil, fuel pressure regulator and CPS. Now it will run for a few seconds then die like the key was turned off. Battery voltage is where it needs to be. Any other ideas or thoughts would be greatly appreciated. I am in desperate mode at this point

Just an FYI, after hitting another JY, the later model Beetles have the right courtesy light.

It was a later model VW Bettle.

I thought the same to but it is a totally different clip.

Totally screwed that one up. Its been edited and the proper clup is shown now.

While looking some things up about the pillar light I came across someone who used VW courtesy lights so I went ahead and grabbed me a set for each MJ at the local pick a part. Not realizing it at the time both sets had different retaining clips. I know i grabbed a set from a newer Passat and a set from a newer Beetle. Both have the exact same part number but different clips. What I really like about them is other then modifying the wiring, the snap right in with no other modification. Here are the 2 different retaining clips, part number, wiring schematic (don't mind my horrible drawing) and the end result.

Been a little while since i have posted but have made some good progress on Sandman. New floor pans installed, POR 15, sound deadening, new carpet, interior is now black and grey, installed factory bucket seats and center console.

I was wondering what down pipe you used for the HO exhaust manifold.
