Hi everyone! I hope y’all can help me solve my issue with my 1997 200 SX SE coupe.
It has the 1.6L engine and is a 5 speed.
I recently purchased this car and it had the CEL or check engine light on.
The part store stated the codes were: P0304 X 2 and P1445.
Here is my problem that occurs mainly once the engine is warmed up- it started bucking and hesitating whenever I push the gas pedal. It doesn’t do it when the engine is cold- at least it is very slight and hard to notice.
On the highway at constant cruising speeds the car rides and purrs great.
While I’m idling at a red light the rpm is constantly dropping about 100 rpm every second.
I have tried the following:
replaced distributor cap. The cap was slightly corroded, IMO
Tested spark plug wires by applying then to metal and looking for spark.
Did a dry compression test and all cyl ranged from 150-160 psi. (Good levels??)
Sprayed carb cleaner around manifold to see if idle changes - nothing
Anyone else have any ideas? Im fairly a novice at mechanics so I’m still learning.
Perhaps the car has stale gas? Not sure how long it has sat, or even if it has been sitting.
bad injector? Bad fuel pump/ filter?
I thank everyone in advance for your wisdom.
