2.4L ld9 1996 Q's

[adelsin]

Mateince Issues:
It stutters and whatnot when you first start it up, but only if you put it in gear. It'll miss and sound like it's clogged, then it'll knock out of it after you give it some gas and be fine. Only when it's cold it does this.

Check Oil light comes on when cold. But if you shut off car, and turn back on, it's gone. ??


Performance:
What can I do? I put AC Delco plugs in it. No cold air intake . What else can I do. Is it possible to supercharge these models or just the 00-02?

you should be able to sc it. it still is a LD9 and if your going to spend that kinda money TC it much better. And as for the probs try diff igniction, sorry not a speller, altornator, maybe? Carb and injector cleaner? Oil pump

sounds like your ignition is taking a poo. new coils + new ignition module + new plug boots should solve your problem.

you can supercharge it. have fun tuning it, however.

Plenty of high power builds have been done on the LD9. Tuning isn't all that bad - go turbo rather than SC, get the SC kit reflash, and get HP Tuners to fine-tune from there. There are several streetable LD9's out there in the 350-450 whp range. If you're willing to keep it under 250 whp, you don't even need to get too involved in the motor as the stock internals are reasonably reliable at that power level and the stock head will flow enough to get you there.

As for "easy" mods - the secret cam swap is cake and adds a few ponies, there are bolt onheaders and exhausts out there, if you can't find a CAI you can mak one easily enough, and the aforementioned HP Tuners suite will allow you to advance the timing and tune the car to make the most of pump premium for a few more ponies. You can find a moddified Quad4 HO intake mani to fit or even do the hed swap to an 086 head (jumps your compression though) for real power. With tuning, secret cams, and bolt-ons combined with mild weght redux you can get her in the low 15 or even high 14 second range reliably.

Your check oil light is the sensor at the bottom of the oil pan is dirty thats what causes he light to come on at first then go off after you restart. It should do the same thing if you just turn the key on for 3 secs then off for 3 secs then start engine and light will go out. The only fix is to drop pan and replace the sensor. Altho it will not hurt the motor as long as you have oil pressure once car is started.
