I remember a guy in the norcal who had the same two tone color Alltrac as you but I highly doubt this is the sameone, still a unique color tho. I wonder if this was a special order type color?

I'm pretty sure it's just faded, not two toned. There are more spots that match than spots that same two toned. It could definitely use some tlc on the exterior.

Slight update: it turns out the timing is a little off. It was really struggling to get moving, so the timing covers came off and sure enough, it looks like its a couple teeth off on the timing. Hopefully we will have it straightened out by the weekend, but we'll see.

Thanks for the comments guys! I'll try to get some better photos in the daylight soon!

Hey guys! I got up to the shop this weekend and put in some hours on the little car. It's running and driving, but not running that well. It has a really high idle (around 1300-1500) but it's steady. The biggest problem is that it has a stutter when you hit the gas. If you rev it up slowly, it is smooth, but if you try to punch it, it falls on it's face. That made it really tough to drive!!

The turbo spools nicely and it's set to the factory settings. I've replaced the spark plugs, wires, and distributer cap. The timing is dead on as well. My brother and I replaced the O rings for the injectors and they are all fresh and clean. It has great oil pressure and the temperature is perfect.

I'm not sure what to check next, but I'm going to order a fuel filter and fuel pressure regulator. It feels like a fuel issue and when we pulled the plugs to replace them, they were pretty white. That means it's running lean, right?

Any thoughts? I'd love to fix the idle and I definitely need to figure out that stutter. On a more fun note, I did weld up my exhaust, mounted and welded my HKS SSQV. It sounds nice and loud (which may get annoying, but it's fun for now).

Here's a quick engine bay photo:

Everything on the inside works, aside from the passenger window. Even the cruise works! My parts car has leather interior, with the leather door panels and stuff, so I started swapping that over too. It's coming along alright, but I'm a little bummed about the way it runs. Any help would be appreciated!!!

Thanks for checking out my little build!

Check carefully for vacuum leaks. I'm also assuming that the timing (mechanical and ignition) are set correctly...

The timing is dead on, both ignition and mechanical. I checked that over and over because there were some issues with it before, so we cleaned that one up. I don't think there are any major vacuum leaks. One of the injectors had a bad O ring and that was creating a vacuum leak, but that's straightened out now.

Is there any adjustment on the throttle body or anywhere else to mechanically adjust the idle?

Both issues were present before the BOV installation. It didn't affect the car at all. It does sound really mean though and I like that a lot :)

It really is fun! I had a Greddy Type S on my 240sx (with an sr20det) and I always thought the whistle was cool at the end. The HKS is a really clean sound, so I'm definitely pleased with it. Now, if I could just get a couple issues ironed out and drive the car, that would be great!

Hey guys! I'm really stuck here! This high idle thing is really driving me nuts. I haven't driven the car any major distance yet, but I'm at a loss. My brother and I have used starter fluid and propane to check for vacuum leaks and we can't find any.

Is there a manual adjustment on the throttle body or anything to adjust the idle? What should I check next? Any help here is greatly appreciated!

Thanks!

Yes there is an idle idjustment screw on the tb, but I would check other possibiltys first. Have you tried swaping out the maf? What about the other sensors did you get them sorted out? Did the car have egr before, did you block it off?

Thanks for the reply! I haven't swapped out the MAF yet, but I have another one to try. The EGR should be all blocked off as well. I'm hoping the MAF fixes it, but I'm not counting on that for sure. I saw something on the bottom of the throttle body that looked like an adjuster, but I wanted to make sure that's what it was before I started messing with it. I changed the throttle body last week and it was the same, so I don't know.

It should have a new fuel filter on it in the next few days, so hopefully that fixes the stutter issue. Thanks for the feedback!

Hey guys!

Quick update: My brother took the gauge cluster apart and replaced the check engine bulb, and sure enough, it came back on. He checked the codes and it only returned two: one for the intercooler (no coolant in it yet) and one for the knock sensor. He went digging for the knock sensor and found the wires going to the connector frayed and not making any connection.

When he went to the parts car to take a look, he found the wiring to have already been replaced with a shielded wire from some sort of kit. He rebuilt the plug and put it together on the grey one and cleared the code. It still idles a little high, but no more code, no more missing, and no more stuttering!

I think the last thing to do before I head up to get it this weekend is to fill the transmission with fluid. It apparently was pretty much empty and making tons of noise when he drove it around the block. Hoping it's only low on fluid and not messed up :).

Alright, that's all I have at the moment. Thanks for looking!

Hey all!

So I went up to Fort Wayne and picked up the car this past weekend and put a quick 150 miles on it. The idle is still around 1400, but I think it is probably a problem with the TPS. It cruised down the highway at 75 mph and did great :).

When I got home, I test-fitted the wheels. It definitely needs spacers in the rear because they rub pretty badly. I ordered some 5 mm spacers to see if they'll help. I know I need more, but I don't want to extend the lugs yet. Here's a quick photo of the test fit:

I also snapped a couple photos while I was swapping the rear seats out of the parts car:

Image

There is still a lot to finish, but it's good to get it on the road. The knock sensor trips every now and then at start-up, but it never stays on. I'm really happy with the way that it runs and drives! The exhaust sounds great and it pulls pretty hard in the first 3 gears, but the highway pulls leaves a lot to be desired.

Next on the to-do list: swap heater controls, install stereo/speakers, install boost controller/turbo timer, and recover the front leather seats. Definitely a long list, but it's getting there!

Cheers!

MY idle it stuck at 1500 ... most likely and bad IAC valve. I unplugged mine for now and if yer not too snappy with the throttle it will keep running. Fast on and off and it may stall. I have seen other people post issues with the ecu causing it ... I havent dug deeper yet ...
