Nissan 200SX Club - South Africa

im from romania and they are few s13 here. im begging u pls help me! the car is a 200sx s13 and has all engine rebuild the problem is that : i have timmed right at 15 grades BTDC with a strobe light and cas is at half .the timing points are correct i have tested all ...when i put the pedal on the floor engine stalls at 3000rps and comes back at 4000rpm .but if i take it slowly it runs fine....now,if i ignore the timing light and turn the cas fully clockwise at the max,the stall disssapears.i have tested everything ,coil,spark plugs,afm,knok sensor,fuel line,tps,coolant sensor an i have that idle problem..pls u ppl are my only hope and i loooove this car.. thx

Hi there and welcome. Awesome to hear from Romania. Remember to send us pics about your sx.

Not that I know what is wrong with your sx, but did you perhaps check ECU fault codes?
Also I hope some other members on this forum will be able to help.
I have also done an engine rebuild and no idling at all.
Do you have a manual of the s13 with you?

When you rebuilt the engine, did you have the block or the head skimmed/shaven at all?

That generally throws out the timing marks on the motor....

Just a thought.

ps: Is your motor a CA18, SR20, RB25/6 ??

yes it has been skimmed 0.05 mm of the block and the problem is not the idle is that my engine stalls at 3000 revs with the pedal down and it makes a wierd sound with backfires,but at 4000revs runs fine until 6000revs, if i take the acceleration slowly the car revs fine,i have cheked the ecu it gives the next faults : 12.(afm) and 13.(coolant sensor) but they are ok i just unnpluged them with the engine on,i have another car for spare parts.and try with other parts an the simptom is the same.i forgot to tell u guys that i dont have any aftermarket parts on it is stock and the head gasket is stock,spark plugs are BOSCH bcpr7+(i think) and they are cooper.last night i have cheked the coils again but not a compromising result. could be the spark plugs???should i take the NGK ones and if so someone give me the correct codes for stock (i dont have the monney for irirdium ones)

I notice a quiet time on our forum, cause of holiday festive season. Be sure there are members that possibly can help. I think the sparkplugs bcpr7 are ok. I use nr 7's. Cheapies are ok. I just replace them regulary.
This rev problem of yours got me!!! Hope that VC and Vlade and others logs on to forum soon to assit.

i forgot to tell u that my turbo is down too is loosing oil on the exhaust part and makes a lot of smoke when i lift the foot of the acceleration,and the fotos will come tonight but i dint put anithing on it (yet) i have buyed the car last month,and love it allready (when the turbo kick in)but hated when lumpy idle and that thing when it stalls at 3000k.overhall i will not sellet soon .and the new turbo will arrive on 24-12-2007 from england just on chrismas eve.thx and hope to find answers here u are the best forum around.AND A HAPPY NWE YEAR TOO U ALL NISSAN LOVERS OUTHERE

you have a really odd problem here, it's as if the ecu map is not coded at 3000rpm... other wise the problem will either be at low rpm or at high rpm

i've had similar issues with my car before, the only difference is that once it hit the point where it wouldnt idle, it went no further. i couldnt rev it up any higher than that point.

your symptoms are strange, but you shouldn't just be unplugging those sensors while the car is running.

as far as i know the two sensors that turn on the limp mode ecu setting are the AFM and the water temp sensor. but then your car wouldnt rev up beyond 3000 anyway.

have you checked your engine earths, and the throttle position sensor. also, have a look in the articles section for the CAS (crank angle sensor) bearing replacement. i took about a month to solve a similar problem, and i checked everything from sensors to wiring harnesses, to ECU, to timing settings. it turned out that the bearings were running in the housings and causing electrical problems. i changed the bearings and BAM...

the problems went away!!!

good luck.

Hey mickey, 2 questions, have you checked your fuel pump and fuel preasure.....if you nose dives when you push and then pulls again this might be the problem.

2nd- is your motor a jap spec CA18DET....with secondary butterflies?

i reckon you're onto something there draco.

mickey, go check those things quick!

Secondary butterflies...? Yeah that sounds like a possible problem.

looking at the pics I'd suggest a decent engine clean first off, then mayeb remove and clean the Intake Mani and all valves, plugs and sensors etc.

Nice to see a black S13. Not many of those in SA.

Here's a VERY VERY important tip that Freddie and I learnt today, AGAIN:

Your FIRST task in troubleshooting problems should be the FULL SERVICE MANUAL.

In your case, read EF & EC-32. Engine stall while accelerating -> EF & EC-58. Possible causes: mixture ratio, ignition sparks (weak, missing), compression pressure low, crank angle sensor, air flow meter, exhaust gas sensor (if you got one).

Follow their troubleshooting guide.

CHECK U RELAYS IT 9965 RELAY DAT COULD BE FAULTY.IM GOT THE SAME PROBLEM

first of all i dont know where the secondary butterflys are (if u have a photo) and second i have posted that i have troubleshot everything (sensors,and cleaned all pipes and sensor) i dont have a oxigen sensor.i have checked all the pages in manual,all sensors are in the right value as the manual says.i forgot to tell u if i rotate the "cas" fully anticlockwise the car runs fine and that stall dissapears(i have double checked the timing belt ) but the timing belt is offset with 20 degres.and where is that releay to check it out a pic maybe .thanx
