Isuzu Trooper 4jx1

[ck030459]

good day tsikoters, i have a 2002 Isuzu trooper 3.0td. I recently brought it to Isuzu davao for checkup they changed the transmision oil and they repacked its bearings. they changed oil, they also change the oil filter and so with the fuel filter, but still I am not satisfied with its poor acceleration which they where not able to sort it out, they advise me that in ordrer to have a much faster acceleration I would need to press the acclerator deeper then release it then press it again, but I was not convinced since it was not the kind of power I had experiencing before, what could went wrong? and what could be your advise. thanks, hope your advise could sort out my problems.

What is the mileage of your Trooper? Marami na kasing reports na bumibigay na yung injection pump ng 4JX1 engine once it reaches 60-70K kms.

Sir Boybi wala po injection pump ang X1 what they have is fuel pump. HEUI na kasi ang ginamit sa fuel system.

ck030459,
Drive by wire na ang gamit ng X1, Try to check the sensors sa accelerator pedal baka loose or marumi.

[ck030459]

its mileage is at 72,500 km. but sa long run it reached a speed of 145. yung problem nya lng talaga is acceleration and uphill climbing mabagal talaga, Isuzu Davao did not report any injection pump problems nung pinacheck namin sakanila, kaya lang yung complain ko hindi nila na solve which is poor acceleration and poor climbing ability. i really doubt whats wrong with the unit wala naman check engine.

Thanks 4Jgtootsie for your advice, il take your advise, hopefully this would help solve the problem.

hate to be the one to break it to you, but for sure bibigay na yung injectors mo.....im sure within the year, mapapagastos ka ng malakai....mga 80,000 worth. ready na your wallet.

Wag naman natin takutin better yet lets do an in depth diagnostics.
ck030459,
How is your oil level lately?
Viscosity of your oil? Smell?
Temperature?
Exhaust odor?
Any noticeable behaviour of the engine that was not present before?

[ck030459]

usually at what mileage bimibigay injectors ng troopers? sabi kase ng Isuzu davao matagal pa raw around 100k+ mileage pa raw, meron ba tayong expert sa isuzu trooper 4jx1 dito sa tsikot whom we could seek for help and advise? thanks

[ck030459]

yung temperature nung last nagoverheat siya at a long distance trip pinacheck sa Isuzu sabi raw yung radiator is marumi pina overhaul yung radiator, then luckily naging ok naman back to normal, then oil level was normal naman, kaya lang mabahu yung yusok niya, i dont know if its normal with Isuzu, and sa engine naman meron siyang nocking sound, and minsan even mataas na yung rpm wla pa ring lakas na lumalabas at 10-40km per hour.

sir, may i suggets ipa tech II mo sa casa.. maybe u have injector probs der... ganyn din trooper namin b4... low power.. mahirapan umabot ng 100+ kms on the speedometer... but since we have replaced the injectors and some sensors.... everything s back to normal .. nakaka 160kms/hr na nga kami... hehehe ... and yup very nice ang ride ng trooper.... u don thave to press it rily hard for acceleration or power.. malakas na ang engine na 4jx1... and aslo u have to consider if your using your trooper mostly sa city driving lang and not much on hiway---- the A/T resets to a low speed mode when always used sa city driving... and hi speed mode if always used on long trips or hi speeds.... waht i do is dat, if our trooepr is always used sa city driving lang.. i would take one satrday to travel and let the car rip tarmak... the following day i used it for city driving, the accelration is good and the engine also sounds good... parang nakapag exercise na din kc ang engine when you use it for hi speeds long trips...

despite ganun an gprob ng injectors sa trooper.. i am a very happy owner of one... i wouldnt replace it for any other jap SUV... the feel and ride and power it has for a diesl engine is excelerating.... marami narin kami offers from frends and other people wanting to buy out trooper. 1 guy even offered to buy it for 1.3m but i declined coz kakaiba tlaga ang trooper.. people would rily look up to you if you would pas by riding in one... hehehe... meron siyang appeal dat it wud make other people turn der heads kung dadaan ang trooper sa road...

sold my 2003 4jx1 trooper last week....dont even ask about the price.
worst ride of my life this 4jx1. it was maintained by isuzu quezon ave, from the time i bought it... all pms done by isuzu q.ave....
i was coming home from batangas when my 4jx1 just stopped after some noise from the engine, i was so scared that i didnt want to start it again for fear of damaging the engine. had to pay for towing back my trooper to the shop.
yup... its those damn injectors... good thing i had it towed. had i insisted on driving it back, the damage would have been worse....

the charge? 80,000 to replace those damn injectors.
guess what guys... isuzu q.ave changed the damn injectors free of charge and labor. after that, i put up the damn 4jx1 for sale. took some time but i got rid of it.

how did i do it? i simply told them that if they would charge me for the injectors, i will do what paul chua did. return the unit and demand for refund.
funny how a the mention of this name brings fear into their customer relations. well they did replace the injectors free of charge.

after reading this thread, im just wondering why the remaining owners of the 4jx1 are still not convinced that there is really a defect in the 4jx1 model. the 4jg2 is the best engine ever. but have you not read from the protest against isuzu thread that there were documented recalls in other countries. this just proves that there is an engine design defect.

i suggest the remaining owners stop dreaming of trying to fix an engine that was recalled by the manufacturers themselves and start thinking of how to sell it while the price is still worth it. if the buyers would know about this defect, then your beloved trooper would surely stay with you forever not to drive around the city, but to look at in your garage.

sell it and buy a toyota or nissan,
