Question about 1988 Suzuki Samurai

2 Answers

My '87 samurai sputters badly when i give it throttle.

When I give it a lot of throttle, “floor it”, while at a cruising speed, all power craps out and it just sputters until I let off the gas. It makes the task of going uphill on a hwy borderline dangerous, because I never know how much throttle I can get away with using.

Try changing the fuel filter.If it is running ok at lower speeds around 50kmh/30mph I would say fuel supply is the problem.
Hope this helps.

Why engine pulses at cruise speed?


old car. If you want simple guessing , just wait it will com.e...
long:
on new cars, it be lack of engine power (or DTCs stored showing bad problems, with LEAN fuel, or EGR stuck open or throttle motor sticking) but back WHEN its vastly more crude and simple and problematic.
I'll answer for USA cars. and stock systems,
all the above same but not throttle elect. motor. no throttle by wire then/.
there are 2 systems, vacuum mech. or electro mech.
one yanks the throttle , the other adds metered air to control speed.
just one glance at it and bingo , post a photo.?

caravan ,not grand caravan
which enigne, of the many, cruise parts can vary by engine type.
my online shows 5 engines and not one PCM has cruise pin(s)
its a separate system then, found in the last chapters in the FSM.
2 possibles.
  • (engine running lean, at cruise, or misfiring) (tune up time>?)
  • or the cruise parts are bad.

id say the cruised servo motor is bad or its valve. sticks.
if parts are sticking clean it , lube it and it might correct.
I do not have access to the servo data. at all.
join a real dodge forum and get that.

1995pontiac,firebird6cyl,sputters at 2000rpm


When you say "sputters at 2000 rpm" , are you referring to ANY time the engine is at 2000 rpm - meaning in Park, when you are just goosing the throttle, or in gear when you are accelerating, or at highway speed in high gear? If you are experiencing a "shuddering" in the engine at certain speeds/rpms - especially if these are speeds you regularly cruise at (long commutes at steady speeds), the problem could be in the Throttle Position Sensor (TPS). They have a tendency to wear unevenly if you drive a certain steady speeds. Eventually, the problem would progress to an engine code, but it may occur without setting the check engine light.

Misses and sputters at certain throttle position


This sounds like the same problem I had with my 87 Jeep 2 door Cherokee Sport.
Thought I had to replace the Fuel pump yet when I went under and pulled it out of the side of the tank I found that one of it's vacuum or return line had fallen/poped off. After I pushed the rubber tube line back on it's metal tube and pushed and remounted the pump back in the tank. Started up and it never ran better at any speed. Yea!!!!!

When accelerating in my 96 5 speed tracker it sputters the whole time. keeps sputtering even at cruising speeds it still sputters when i hit the gas.


Is your check engine light on ? Should be on dash a yellow light that says (check engine soon) If it is go to your local Auro Zone and they will run a code scanner and give you a detailed readout on paper as to what the codes say is the problem,,,,,,,,,,,,,Im thinking your oxy sensors are bad, But you go check it out.

Sputtering


Have You Changed The fuel filter? Surging at higher speeds or cruising speeds, My guess is fuel filter.

95 geo tracker runs fine but bucks or surges at 25/30 mph slow cruise accelerates like rocket.


8valve or 16v valves, big diff !

bucks, needs a tune up.
surges are too lean .
for surge check fuel pressure.

i think you mean Wide Open throttle has full power
right.?

if yes , the fuel pressure is ok
and the MAF is bad on a 16v
or you have an air leak.

tell more , get more.
