I have a 90 conv. that has a code 33 Map voltege high that only occurs when the ac is on. the car will stumble and act like it wants to die right before light comes on, then goes off and run fine after that. have changed; map sensor, iac, tps, and egr all over the last year and still has this problem. vacuum at idle is 22 and with ac on is 19 or 20. iam at my end with this.could it be the ecm? thanks for letting me post..Oh forgot to mension, fuel injectors, bosh 3, new pump and regulator. fp is 34 to36 at idle. thanks.. |
