My 89 Olds Delta 88 still had a small miss compare to how it was running before
I have been repairing my 89 Olds Delta 88 on and off for the last 2 years I have had it. Well as of last Friday I replaced the Idle Air Control Valve (IAC), Cam and Crankshaft sensors and it made it run a little bit better buy taking out about 80 percent of the miss and shack it had when I was at a light or a stop sign. Well there is still a problem but I don't know what else it may be. So is it time for me to pay a shop to fix it or due yall think yall might be able to help me with it. I will list everything I have done below to it.
Here is the list.
Spark Plugs, Wires and a new Coil Pack about 6 months ago
O2 sensor About a year ago
Replaced the Intake Manifold Gasket, Fuel Filter and Air Filter about 3 months ago
New Fuel Injectors and Pressure Regulator about a year ago
New Shocks and Struts about a year and a half ago
Front and Rear Ball Joints
Inner and Outer Tie Rods in the front end
I have done more to it but I didn't want to bore yall so I gave the basics of what I have done so maybe yall might have a better chance at helping me with this. Thanks.
