i have a 1989 lx sport with 140,000 on the car, i bought it in 2001 with around 92,000 on it. for five years now the car will have a surge in the idle quality that will accelerate the car, or it will misfire like it has no fuel on cold start up. i have changed the following:
1. fuel filter
2. fuel pressure regulator
3. tps
4. tfi
5 coils, caps, rotors, plugs wires like every three months
6. mass air flow
7 egr vacuum sensor
8 egr valve
9 pcv valve
10. idle air control
11. air check valve
12. air charge sensor
13. coolant temp sensor
14. o2 sensor
15. clean throttle body
the only thing i have not changed is the fuel pump, fuel filters, or the map sensor. the original motor was replaced in 1996 by the dealer and the original owner said ever since then it has had the idle problem with no luck fixing it. the fuel gauge has never worked on the car since i had it. the check engine codes will throw either a lean condition while de-celerating, or hot idle, or will throw an egr code but has had three new egr valves on it. im about to sell the car and would like to find out really whats wrong with this car. i am thinking it has been possessed. i have dumped so much money into! here is the kicker, it really misfires when it is wet. now you can sit and dump gallons of water onto the plug wires cap coil and tfi with not even a hesitation or a back fire. but dump a glass on water down behind the hood where the wipers are as to let the water run down the firewall, thats when it will misfire and chug like its getting no gas. but take it to the dealer or another garage and they cannot find anything wrong, it wont even throw a code. so im at my last nerve.
