Bad Mass air flow sensor, fuel pressure regulator may be leaking, fuel injectors may be bad, oxygen sensor. Is your check engine light on? If so, stop by autozone and they should scan it for you for free
The ABS sensor is built in to the wheel hub, if its bad, you have to replace the whole wheel hub, they run about $90-120 depending on brand and where you get it.
A serpentine belt run multiple auxiliary applications (IE AC, Power Steering, Alternator)
It will run, But not right and the check engine light will come on. It needs the converter.
That would probably cause it to run lean.
These leak sometimes. Its regulates the pressure to the injectors. It is located inside the plenum part of the intake manifold. You have to take Plenum off to service. You know when they leak because you car is hard to start and appears to run rich at startup. Can also cause your car to run rich while driving because fuel is essentially leaking in the the manifold in drops.
No it will not. The 1990 engine is all together different and yes it will bolt in But it will not run. You need a VORTEC engine from the year 1996 through 1999.
my truck was doing the same thing before i had the choke set right, because it was partially closed, making it flood out and run rich
Yes it will fit in there. But it will never run. That 99 engine requires a COMPUTER to even run right.
YES it will. It will either run RICH or LEAN. Must repair.
Most automotive parts stores will run a diagnostic check, free or charge.
probably with alot of modifiacton ie: new motor
yes, otherwise the engine will run too cool and you will get horrible gas mileage
