View Full Version : I believe I have a distributor problem...

So today I started my N/a-T with the XS Power kit and I had a few problems. The first thing I noticed right off the bat was the check engine light was on. I didn't think much of it only cause I thought it was a sensor since the car was running just fine.

So I backed it out onto the street and went to give it a test drive around the block and I made my first turn and it spooled very nice and very fast (compared to stock) and it blew off. I did this twice and on the third time the car just shut off. The power steering gave out and all my lights went on as if I was ready to be started. I managed to get the car started quite easy and drove it in very low RPMs home.

I adjusted the timing so it was all set and felt it was time for another test run. So I took it around the block and it didn't die on me but the turbo now was not spooling. No waste gate and no spool or blow off. Still check engine obviously.

So I took it back home where it's sitting now and I am looking over it and one of the bolts on the waste gate came all the way off so I am thinking that is why I am not spooling. I still want to get the timing perfect once more and I checked my turbo and it's all fine inside. The fan blades turn very nicely with ease which supports my theory on that waste gate bolt being the spool issue considering it did spool once.

My kit seems to be in perfect running order. I have the oil inlet and outlet in the turbo and tested both ends and they work great. I have all the inter cooler pipes run free and clean. The headers and turbo as well as down are bolted into place nice and tight. waste gate had that once bolt issue (it was the bolt I could not fit the lock washer on). Dump tube is nice and tight. All vacuum lines are connected properly as well as the sensors. I have my MAF connected to a 3'' pipe with a filter on the turbo. My distributor cap is the one from the 4-runner and it seems to be hooked up alright but I am not quite sure there. That is the only thing I am truly uncomfortable with.

I'll try to get pics up tomorrow asap. If anyone has had the same or similar problems what did you do to correct this? I am open for ideas and suggestions but in the mean time I am going to try the stock timing settings with the stock distributor cap minus the MAF and 3'' with the filter.

I'd like to get the check engine light to turn off, the timing and firing order nice and clean, and the turbo to spool obviously ;)

So anything that could possibly help would be greatly appreciated. I'll keep everyone posted. Thanks.

Did you diagnose to see what the check engine light is calling out?

Ok so I got my engine code and it said that one of my vacuum lines was off so I redid the the vacuum lines to make sure they were good and sure enough they were not perfect.

The check engine light and [!] warning light are off. So I test drove the car around the block and it spools nice and man that waste gate is loud lol. So my check engine is all off and my spool is exactly where it should be.

I have a minor problem still though. I have rotated the distributor and it is still 5 degrees off timing. I am not exactly sure how I can rotate it any more because its pretty maxed with the 4-runner cap.

I turned my idle up so that it doesn't die on my. It is at about 700 or so RPMS. The big issue with the timing is that the car stalls out when I come to a stop. As long as I keep on the gas it runs really clean. Even when I push in the clutch it stalls.

So any ideas on how I can get that 5 more degrees on the 4-runner. If so then I will be in business to move onto the ecu and fuel pump.

Sorry again about pics. I am working on getting them asap. Probably tonight.

pull the distributor, skip a tooth and you should be able to regain the adjustment in the opposite direction.

Make sense?

Yeah I actually did try that and on either side it was too far off, I couldn't even find the mark. Have you successfully done that?

I am willing to try again.

Seems like you need to restab the distributor. How did you check timing? Did you put the car in diagnostic mode first? Put the motor on TDC and pull the distributor cap and make sure the rotor is pointing to #1.

Okay, so here is my up date for the day :D

The timing is right on track. I mistakenly skipped 2 teeth yesterday when rotating the distributor so my fault on that.

I have no check engine like originally and the car seems to be running great.

I however still have a tiny tiny detailed problem. My idle sometimes drops a little low and when I take off, for example I ease off and am cruising at 3k RPMs and then take of to about 6k RPMs and then press in the clutch my RPMs drop and drop too low and my cars stalls out, just as if you randomly took your foot off the clutch.

So has anyone had this problem? I know my timing is right, my vacuum is correct and everything seems in order. So I am not sure what gives.

I can keep the car alive when stopping quickly, by tapping on the gas pedal and holding it up till I stop.

When the car sits and is on it seems perfect. When I take off and shift real quick I have no complaints. It's just the RMPs dropping when I stop too quickly and it didn't do this when I was stock.

I talked to my dad today and he suggested getting a tune up and maybe a piggy back ECU to solve that issue, which I was planning on doing but not this soon. Does anyone second that idea? I know this is no longer a distributor problem but I'd love to get in all in order.

Thanks

Finally got some pictures up. I know, it's a little dirty, but I haven't had time to wash it since I started the turbo project.

The first pic of the maf is scary, but then when scroll down, I see the rest - it looks really nice. Nice job on the brackets, etc. That oil drain is a little sketchy, you don't want any horizontal sections or you WILL damage your turbo.

You need to have some sort of fuel tuning device, I suggest SAFC2 or SAFCNeo since you are keeping the MAF, this will help you with the stalling issue. A better solution would be to run the MAPECU1 which deletes the MAF entirely.

Thanks,
Mark

I am just going to lose the MAF and I already ordered my MAPECU1 now, should be here soon.

In the mean time I'll adjust that oil return cause I don't want my turbo damaged and I will let you know how everything works out when my fuel tuner comes.

Thanks Mark,

Looks like a nice setup. Your BOV is causing your stalling issues. Map-Ecu will solve it.

Okay great! Thanks guys! Should be here soon.
