I have a 96 Civic CX hatch
Just finished (1 month ago) swapping in a ODB1 GSR, Wired in the Vtec, butterfly and associated wires but it still isn’t working right
When the car is started is does the following
- Has trouble idling
- Makes a loud clicking sound (Sounds like the butterfly is opening then slamming closed)
- Idles around 500 RPM and wavers up and down buy 300 RPM
- Stalls out at times.
- Check engine light has code 20,21, 41
- No power, feels like the old 100Hp engine
- No Vtec
- If I give it gas to get it to 1000-2000 rpm it will idle better but still wavers the RPM up and down about 300 RPM.
Here is the kicker, after about 5 minutes (gets warm) all the problems go away but I still don’t have power in the car. (Check engine light is still on)
Here’s my question
- If Vtec isn’t working does the car go into limp mode?
- If the Vtec solenoid was broken would it do this?
- Has anyone seen this before.
I have checked for vacuum leaks and had the ECU replaced. A shop that does swaps all the time has had the car for a week or so and they are still scratching their heads.
Any help would be appreciated... $5000 swap is now over $6500.... and I still don’t have my car back
