SES light
I had my '92 modded a couple of years ago by a known tuner but I wasn't real happy with some of the results, (rough idle and backfire) so I had Haibeck retune an extra e-prom I had for me to see if I got different results. The mods were;
Ported heads, injector housings and plenum SW headers no cats Corsa exaust 3:92 gears Reset cams and I added K& N filter Relocated temp sensor The Idle is smooth and the backfire is gone but with a hard shift above 6k I get a momentary SES light. Using Gordan's kit I could not find any stored codes, Marc set fuel scheduling for 410/420hp. Any ideas? |

vac leak

Re: SES light
It could be you are running out of vacuum and it's setting a DTC 61 intermittently ?? You said hard run to 6+k rpms, and that would be where the manifold vac drops almost to zero and in theory our vacuum pump is supposed to pick up any shortage of vacuum in the system to keep the 2* actuators pulling on the 2* linkage.
Not to be a wise guy, did you use the Gordon jumper for the CCM? I think that's where the history codes and intermittent codes are stored....I think!:o :cheers: Tom |
Re: SES light
I tried them all, ECM, CCM etc; nothing. If it is a vacuum leak I wonder why it didn't show up with the other e-prom? But, I'll check all the vacuum lines.

Re: SES light
My guess would be a lazy secondary vaccumm actuator under the plenum. One of the pair
