Record by record
3 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.
Component named as the cause
How it is said to have ended
- result not stated3
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

What the documents say to do
Intake manifold gasket leak (cold idle misfire, lean codes)Confirm
- The seals may leak around the bottom side of the port, which makes the vacuum leak hard to detect.
Repair
- Only the current teal green gaskets should be used; the old gaskets were orange.
- The intake bolts must be replaced and not reused.
Caution
- Do not measure the intake manifold across all four intake runner ports.
