  1. it be nice if i find one that can help service the old Z plus newer cars. im a computer geek, so i will figure it out, but i just need help deciding what is suitable for the older cars. whats specs should i be looking for on an Oscilloscope
  2. Hope all is well guys and that you've enjoyed your time off. looking to get an Oscilloscope, but have no clue what to look for. can some one suggest? here is what i was able to find, but again dont know if these do the job 1) https://www.newark.com/seeed-studio/72-12875/dso-nano-v3-pocket-oscilloscope/dp/68Y0128?gclid=CjwKCAiA-_L9BRBQEiwA-bm5fjOE1QC3fUbg-vWRA5kdWtLGnkpvvtyINIYi-STskBdJBexp00e3RhoCQ_oQAvD_BwE&mckv=sPUiaKi4F_dc|pcrid|434136793584|plid||kword||match||slid||product|68Y0128|pgrid|100464452106|ptaid|pla-901419072616|&CMP=KNC-GUSA-GEN-Shopping-NewStructure-Test-Measurement 2) https://www.amazon.com/YEAPOOK-Handheld-Oscilloscope-Professional-Bandwidth/dp/B07XBL4BTL/ref=pd_di_sccai_3/147-0082242-3185004?_encoding=UTF8&pd_rd_i=B07XBL4BTL&pd_rd_r=afd74d7c-c862-40f9-8032-52347d418724&pd_rd_w=Gl4OZ&pd_rd_wg=x4eV9&pf_rd_p=c9443270-b914-4430-a90b-72e3e7e784e0&pf_rd_r=TFXYPBH2V944PRH3ZCDX&psc=1&refRID=TFXYPBH2V944PRH3ZCDX 3) https://www.amazon.com/Hantek-Oscilloscope-Generator-Multimeter-Multifunction/dp/B07MQJR6W9/ref=asc_df_B07MQJR6W9/?tag=hyprod-20&linkCode=df0&hvadid=343187910376&hvpos=&hvnetw=g&hvrand=13656858700912694070&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1022331&hvtargid=pla-726785581902&psc=1&tag=&ref=&adgrpid=69721953515&hvpone=&hvptwo=&hvadid=343187910376&hvpos=&hvnetw=g&hvrand=13656858700912694070&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1022331&hvtargid=pla-726785581902
  3. tnx for the reading material. im on the zCarDepot placing order for injector, CAP, Rotor & new basic NGK plugs.
  4. Guys, anyone knows about the reference signal? i was reading somewhere that there is a 5v signal that must be available at all times. it's originally an AC signal that comes from the Crank Sensor to ICM, then ICM converts it to a digital Sig that the ECU can benefit from. i have no clue where i can chk for that on the ZX
  5. im a huge fan of keeping it original but if there is a benefit in upgrading ECU, i wouldn't mind it. some upgrades are healthy and do increase car safety and efficiency send some suggestions pls
  6. i hear ya, but the injector does spray. so could it be something else in the injector that is malfunction?
  7. i had previously put a link for the injector i purchased and it was for sure fit for the turbo model. can some one recommend a brand? tnx
  8. Hey JSM, and tnx for sharing. my ECU was replaced by my trusted mechanic few years ago. my dad accidently plugged the battery backwards and fried few things. several parts were replaced at that point. one of which the distributor. im pretty confident its a healthy ECU but i don't have a way to prove that. as for the connectors, they are nicely snug and safely covered. i dont mind upgrading connectors if u have link for one.
  9. i swapped inject6 w inject 5, and the problem followed. as soon as i unplug harness on any injector engine will act up except on the new injector which i snow in position number 5. So even though it sprays can it be a bad injector? Whats next?
  10. not sure which oscilloscope to look for.. id appreciate it if one can be recommended on amazon or ebay. i see digital ones, some say for car audio, others diode testers. DC/AC
  11. i could swear i uploaded some stuff last night. couple of short videos showing car idle after 15min warm up starting to show blimps and missing. Then cap was raised, car ran for 2 hours almost w no signs of any idle issues. unplugging inj 6 made no diff, while unplugging others clearly showed a difference. there is an incredible amount of exhaust smell to the point i take outside of the garage immediately. you can smell that even outside in the open. is there a video or steps to help conduct a signal test? could it be the ignition is not sending correct signal to ECU? 15min_after_first_start.MOV disabling_injecters.MOV IMG_9291.MOV
  12. haven tired that. i can give a try but someone here asked me to keep it tight as it should be need to figure out why inject 6 doesn't make a diff when unplugged. i do recall inector 6 making some diff when cap was raised. it was very minimal change compared to other injectors however, i was able to notice a change in engine sound Zed, do u have answer for 3 , 4 or 5? tnx
  13. Hey guys... 1) attached is pic for the battery connector i used. i measure ohms on cables with out having this installed and i get 0 ohms almost on all connections (on screw below batter tray, on intake manifold screw, as well as the starter screw). after installing the connector i do see ohm reading of about 1~5 ohms depending where you touch. Battery leads have been cleaned very well w sand paper. 2) one connector below the fan was very oily. cleaned it up pretty good 3) found one loose red & yellow connector 4) Cut wires (black , Black/Brown). its obvious they were cut w a sharp object as they are very clean cut 5) what are these 2 sensors? as of now, condition is the same. once the car is warmed up the idle has some blimps and missing. unplugging injector 6 still has no effect on engine sound, or idling. not sure whats next
  14. yeah..thats true about my Ohm meter. back in collage i did a lot of motherboard testing and soldering. so im aware of touching the leads before measureing i'm hopping Friday will be warm enough for me to do more tracing. if anyone has pics of firewall spots to test or connect to that be cool
  15. yup, will get a new one and test in a day or so. it should warm up in NJ on Friday
