Question about Bulldog Remote Starter & T-Harness Kit for 95-03 Chevy Blazer/Chevy S-10 Pi
The service eng light stays on scaned the truck and it gave two 2-digit codes the first one 42 and also 44 code 42 = bypass or electronic spark timing (est) circuit 44= oxygen sensor or circuit lean exhaust detected so my question is does any one know how you would go about trying to pin point the problem or is there something that would be likeley to trigger codes 42 & 44 thanks for your time
The second code is generated by the first... since you have spark issues it causes the truck to run lean which in turn causes the lean exhaust code to show up... check your ignition coil, plugs and plug wires... your problem is more than likely in one of if not all of those areas...
