So I put a Z6 head on a 1.5 block (92 CX hatch).... It starts and runs but craps out after warm up. Already put correct dizzy and ecu (stock p28) on it. Timing on belt side seems to be correct. Just found out that it's only running on three cylinders (1,2, and 3). Spark test OK... Injector...
I did a little more work on the car recently... It IS throwing a code now but only one... Throttle position sensor... we all doubt that the TPS would make it crap like that after running for several minutes... Tried a different camgear but that didn't help... checked all the vacuum lines for...
It idles a bit rough but no backfiring, when it craps out it just coughs and puts a bunch, like it's trying to keep going but cant... Put it this way, if it didn't bog down after a few minutes I would just set the idle and run it like that... no missing that I can tell as of yet... It just won't...
At first it idles a bit high, and just drops as it continues to warm.... we haven't set the idle on it yet though. waiting to get it to keep running first.
Thanks for the suggestions... I'll update after I put on the new distro and camgear (also going to check vacuum routing and check for intake leaks)....
My 89 hatch has a blown steering gear box.. need a new rack but don't want to drop $200 for it.... my buddy has a 89 crx with manual steering on the scrap heap... anybody know if I can use the rack off the crx for my dx hatch? :huh:
Is there anywhere online that I can find schematics for vacuum line routes for a head swap such as this? If I could print something out it would make it super easy to determine whether or not routing is an issue....
So... We're still hunting down another distro, but we did get new cam gear (before we had the cx camgear on the z6 head) just to be sure... I plan on checking for vacuum issues when we go back to work on it and we're going to test for codes again as well... My "teacher" in all of this is almost...
So i did a swap on my 92 cx... put a d16z6 head on the cx block... she starts and runs when cold, but as the engine warms up the idle just keeps going down and down and down until it sputters and takes a big crap... this takes place over the course of about 3-4 minutes, from start to crap, that...
