Wonder if any of you guys can help?
My 1997 MPI recently came out of the garage due to starting problems. In short, he was very unwillingly starting on about the seventh try, or sometimes not at all.
The garage struggled to diagnose the problem. Although they have undoubtedly improved the starting, he now only starts with the throttle depressed at least half way, whereas before the original problem, he was starting with no need to depress the throttle at all. Once started, he runs fine.
With my limited knowledge, depressing the throttle on an MPI is simply allowing more air into the engine. So does this workaround indicate that not enough air is getting in to start it?
As an FYI, the garage replaced the coolant sensor, crankshaft sensor, and the throttle body (the previous one wasn't closing properly). They also had all electrics checked, twice.
Any advice or pointers gratefully received.
