Secondary problems

[89SHO X2]

Car runs very good at idle also has smooth accel. When the secondaries kick in and it bogs down then has a rough point. After all that it opens up and accelerates fine. Never done that before. I fixed a lot of others I had wrong . And it ran like new for about a month. Replacing the fuel filter after I run some Tune-up in a Bottle though it. Fuel pressure is 30 at idle and 38 on acceleration. Plugs replaced. Wires gone though for cracks and such. Replacing soon. Have any part I need to replace on my other 89 SHO. Thanks for viewing!

Have you replaced your cats? But it could be your wires are old and need to be replaced, or the o2s? OH and pull your codes

Clean you MAF sensor elements. I almost guarantee it.

If you want to check, just unplug the sensor, start the car, and drive around for a few minutes. It won't hurt anything to have the sensor unplugged and, if it's the cause of your bogging, will run out nice and smooth.

It might run so good, you'll drive it right up to the auto parts store with the sensor unplugged to by some cleaner.
