1.6 L 4A-GE DOHC I4 (AW11)
wiki (USA)
As a power plant, Toyota chose to use the naturally aspirated 4A-GE 1,587 cc inline-four engine, a dual overhead-cam, four-valve-per-cylinder motor.[5] This engine was also equipped with DENSO electronic port fuel injection and a variable intake geometry ("T-VIS"), giving the engine a maximum power output of 112 hp
first what engine then what fuel injection.
Study the Denso system first, then trouble shoot.
If I had this, car i'd :
1: make brakes perfect.
2: fix all fuel leaks, every inch checked,!!!! top reason for midengine car fires...
3: compression on all cylinders (WOT) 150PSI or more.
4: full tune up with all fluids. really !
5: i'd then check all the EFI sensors and have the the injectors pro cleaned off car, (sonic cleaned)
6: engine thermosat holding water temp at 180F or more steady!!!
7: back flush every inch of cooling system and sub parts.
after all that id diagnose it.
starting with fuel pressure tests , all 6 of them.
ask.
TSB's the update MR2 engine signal (spark) generators (sensor)
old ones are no good.
bid away

now the MPG bad list, its huge, but will do short list, brakes drag? transmission slipping got M/T? engine is bad, so low compression, bad spark (tuneup) bad fueling, (lots of tests) and fuel pressure on the moon, not 30 psi , but 60, bad reg. leaking or clogged injectors. lots more.
CEL lamp glows running engine, pull the DTCs, using the jumper for ECU. see next link for free books. see pdf shop manual.
