Hello, I recently had my engine replaced with another d16 non-vtec. After driving my engine in for 2 days my Speedometer starts jumping then completely stops working, check engine light comes on and when I stop at traffic lights my idle fluctuates from around 0 - 200 revs as if its trying to keep itself from stalling. I have my old transmission and throttle body on this new engine, also this happens at any time of the day after the engine warms up.
Do you
have the same problem?

What you need to do is have the computer scanned for codes. If the light has come on, there should be a trouble code stored in the computer. Most parts stores will do it for free. Have that done and let me know what you find so I can better help. Also, did all other sensors plug and go? Was the VSS reconnected correctly or could it be loose? Allso, check for vacuum leaks.

Let me know what you find.

Check for codes since you have check engine light on codes must point to troubled area

The code is 17 I did it myself by linking the OBDII connector plug together with a paperclip. The CEL light Flashed once for a few seconds then 7 blinks after, which gives me code 17. That comes under VSS.
The other day when I was driving everything was fine untill it got a little dark and I turned my lights on and my speedometer started bounces and eventually stopped working.

DTC P0500 & P0501: VEHICLE SPEED SENSOR (VSS) MALFUNCTION
D16Y5 M/T
Test drive vehicle. Using scan tool, check vehicle speed. If correct speed is not indicated, go to next step. If correct speed is indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at VSS and PCM connectors. See appropriate wiring diagram in WIRING DIAGRAMS article. Repair as necessary.
Turn ignition off. Block rear wheels and set parking brake. Raise and support front of vehicle. Turn ignition on. Block right front wheel and slowly rotate left front wheel by hand. Using backprobe set, measure voltage between PCM 32-pin connector "A" terminal No. 9 (Brown/Black wire) and PCM 31-pin connector "C" terminal No. 18 (Blue/White wire). See Fig.
If voltage does not pulse between zero and 5 volts, go to next step. If voltage pulses between zero and 5 volts, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM.
Turn ignition off. Disconnect PCM 31-pin connector "C". Turn ignition on. Block right front wheel and slowly rotate left front wheel by hand. Using backprobe set, measure voltage between PCM 32-pin connector "A" terminal No. 9 (Brown/Black wire) and PCM 31-pin harness connector "C" terminal No. 18 (Blue/White wire). If voltage pulses between zero and 5 volts, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM. If voltage does not pulse between zero and 5 volts, check for short in Blue/White wire between PCM, TCM and VSS. Also check for open in Blue/White wire between PCM and VSS. See appropriate wiring diagram in WIRING DIAGRAMS article. If wire is okay, check VSS.
