I think more symptoms are needed here. Why do you think you are in limp home mode? When does it happen? What other things seem to be wrong? You might first want to reset the ECU by removing dome light to reset and then see if ECU is throwing codes. Give as many details as you can...
'91 Tracker 8V, 1.6L, 5 sp, 4wd, 2dr, conv, CAMI, horribly rusty
'97 Suzuki Vitara 8v, parts car - worth its weight in gold.....
'61 NSU Quickly - 150mpg
car in vin tagged Geo Tracker, btw (wow a profile blush)
for get the CEL, it is set to loose spec.
connect any quality scan tool/ reader and look at Pending codes.
or a real scan tool and look at the sensors.
2 ECT stuck at -40C
fuel pressure on the moon, like 60psi.
ever tune it up.?
does the CEL lamp come on kEYON , no start.
and then go out after starting?
the pending codes will be p0400 or P0300 ,301,302,303, and 304.
or pending MAF, TPS, or others. never use the CEL to trouble shoot.
the CEL is for for people that drive the bad running car for so long the they are dumping tons of crap into the atmospere.
look as sensor data live.
