1989 Isuzu I-Mark RS from North America - Comments

My computer packed it in after 2 yrs. of ownership. I was driving one day and my I-mark suddenly died while I was driving on a main road, then everything shut off. I was able to start it again, about half a block later it coughed then died again. The computer has been replaced and I have had no problems since.

Idle control is a big problem with isuzu's (I-mark, Impulse, Storm, Stylus). My car will sometimes stall for no reason when I'm stopped. The idle has a tendency to be inconsistent, it will idle really high then drop low to the point where it will almost stall or completely stall. That sucks because I'm putting unecessary wear on my starter. Isuzu dealerships could not figure out the problem (dumbasses). My mechanic simply adjusted the THROTTLE LINKAGE and magic! the stalling stopped

and the erratic idle isn't as bad as before. I hope this will solve the stall/idle problems for Isuzu owners.

Other than the problems above, this car is very reliable. I've owned it for 8 yrs and all I had to do is regular maintenance oil changes, tune-ups and other. Parts for me, are still easy to find thanks to my mechanic's contacts all throughout canada, u.s., and japan. As for performance it pulls pretty hard after 3000 rpm and I have taken it up to 8000 rpm no problem. I think these lack in the torque department and could use some. The motor is a factory high compression 1.6L DOHC producing 130 hp, but feels like 190 hp. The suspension of these cars cannot be compared, the I-mark suspension was done by Lotus. When you take this car around corners and especially S curves it's awesome! As for races, I have beaten many cars and at the same time have lost too many. These cars have to have the best gas mileage, under $30 to fill it full tank. I am very happy with this car and hope to have forever!

I too own an '89 Isuzu I-Mark RS. I have driven it for about two months and the clutch went out. Now I am having problems finding a clutch kit under $180.00. My Isuzu also has the erratic idling problem so i'll try the throttle linkage and see if it helps. These cars are very rare and will be worth something someday.

I have an 89 I-Mark RS. I love this car! It's great! I have the idling problem too, but it's not that bad. Only when there is a traffic jam does it give me any problems. However, like the first comment, my car just died right there on the main road. I'm told I too need a new computer. I'm having a hard time finding one. The garage that has my car received 2 different computers that their systems says should be compatible, but unfortunately neither is. I have thus far been without my car for 2 months! I need to get back to work and school! Can anybody help me out in where to find this computer?

I bought a 1989 1/2 (yes 1/2) I-Mark with 1 mile on it in 1989.

I loved that car!!! It was perfect for everything I did. It was excellent for travelling, as the trunk was spacious. It could handle camping equipment, 2 sets of scuba gear and food for a week.

I wish I still had it, but it met an untimely death.. boo hoo.
