Sluggish/bogging poor acceleration issues

By mhunter90
- Sun Apr 12, 2015 10:08 pm #353116 I have a 95 lx auto sedan that was very poorly taken care of..all stock except ebay catback and crappy intake someone put on...Ive done routine maintenance. oil change, plugs and wires ,cap and rotor, new fuel filter. and still not sure whats going on. I know these cars don't have a lot of power but I can literally floor it from a stop and it just bogs and I barely move until the rpms finally get up high like 3500-4k and then it takes off a lot quicker...any suggestions?

i know you said that there is a AM intake, but how is the filter condition? clogged cat/bad o2? dirty fuel injectors? exhaust leaks?

those will make a car feel weak.

take off the heat shield on the manifold and make sure it isnt cracked. (since its free)

ive had very poor performance and found out that the manifold is cracked causing a good exhaust leak which made the car feel like a snail

..good points..i think the air filter is fine..i swapped the cat out for a test pipe already thinking it was possibly clogged.im not sure how to check the injectors and I havmt checked the manifold for leaks but I will do that though I dont really hear any leaks

This will also give you the opportunity to check the condition of the timing belt, something you need to do when you buy a used car. Especially one that's been neglected.

It's quite clear that your cam timing is off. It's too bad that you changed your plug wires and other items unnecessarily (you should test wires before replacing them).

what makes you say that?? This is an issue ive had from the get go even before the water pump and timing belt was changed..also it wasnt unnecessary. The car was neglected. Changing those things made it run a little better.
