This Honda had been in a crash and repaired, but it still had a running problem. It would start, rev high and then stall. It was towed to our Hamilton workshop so we could investigate.
Finding the leak
Once we checked the car and confirmed what it was doing, the behaviour pointed us towards a large intake air leak. We carried out a smoke test, which made the problem visible: the intake manifold had split in the crash.
The smoke in the photos is from that diagnostic test. It helped us locate the leak rather than guess at which part needed replacing.
The repair
We replaced the damaged intake manifold, and that resolved the starting, high-revving and stalling problem.
This job is a useful reminder of why diagnosis starts with checking the exact symptom. Understanding what the car is doing and choosing a test to investigate it helped us find the cause.
