142g;

Base injection pulses are a result of contact closures from Distributor contacts. Pulses resulting from opening Throttle are from contact closures of the comb contacts in TPS, both function similarly as far as the hardware goes (both are inputs to RS Flip-Flops in ECU), but otherwise quite a different thing...and the later can work fine during tests (should be 20 pulses!), even if the former is not working...BOTH need to work for normal function and good throttle response...and complicating things further is that the TPS is not even necessary for engine to run...the MAP sensor supplies ECU with enough info with which to supply a base fuel amount, even at various Throttle openings...TPS only allows improved throttle response with quick Throttle opening...as a D-Jet experienced guy, you probably are aware of these things, I'm reiterating them here more for Rob's info...

Cheers
