My swap has been up and running for about a month and a half now starts great, idles great, love the power. However I keep getting a CEL when I really lay into it, seems to happen momentarily if I hit 6000 rpms on a hard launch. Sometimes it will stay on sometimes it goes away right away, other times it will come on and stay on for a while after a long full throttle run i.e. up a hill not necesarily at high rpms.
I'm thinking it must be a 1222 code. Which makes me wonder about my fuel injectors, since I never got them cleaned before installing them, corner cutting=bad
The problem is I can't get my CEL to flash the codes anymore, I don't really know what's happening there
I just checked the TPS out:
5 VDC in with the key on between 1and 3 on the connector.
3.76Kohm between 1 and 3 of the sensor
1.2kohm-4.2kohm between 1 and 2 with the throttle moving.
Would that 200 ohm difference affect the CEL not being triggered or is it maybe the DME that is making it not flash codes?
Just as a backstory I was having problems with the fuel injector connectors making bad contacts on the injectors (no clips on the plugs) this was giving me CEL's for injector ouput stage and individual injectors once in a while. It would miss on the affected cylinder (obviously since no fuel was going in) so it was easy to identify. With this new problem I cannot detect any misfiring.
Any ideas?
I need to find someone with a Peake scanner in my area to figure out what the CEL even is, I guess that is the next step.
