engine noise

tkozaki1 · 9-9-07, 13:23

I looked through the archives and didn't find my exact problem. I started to hear a lot of suspension noise several weeks ago going over bumps. I replaced lower ball joints, tie rods, and sway bar links before the suspension noise. Now I am getting an engine surge while i'm just cruising and not accelerating. It has been getting worse the last few days. Today I checked just reving the motor in neutral. I got the surge at a constant RPM. Also the higher the RPM the worse the surging. During the surge, the engine is making a lot of noise. I checked the spark plugs and they look like each one is firing good. I will sometimes get a clunk noise when I press in the clutch but not always. I was wondering if anyone had any ideas?

Sounds like the whole car is wrecked. Sell it.

I've got that same "surge" of power thing while either idleing or cruising, but it's not consistant, and i can't predict when it will happen. However, i do hear what sounds like a pump or a fan start up in the engine when this is happening. It doesn't appear that there are any misfires during this time. Like you ... i'm stumped

Have you checked for intake leaks. Sometimes they will make the engine shoot up in rpm because it detects more air and sends more fuel.

uh i heard that air bubbles in the coolant will do the idle surge i dunno bout crusing though. My car has that problem and i'm too lazy to check it out. It got better after i seafoamed my engine though

Just giving you guys an update on my problem. I found the engine surging problem to be the spark plugs and wires. Once I changed those I haven't had any problems with the engine surging at cruise speed.

I still haven't found my suspension noise. I did buy some new moog sway bar endlinks awhile back. From what I remember they are thicker than the original ones. I thought those might be hitting the control arm. There looks like to be a little mark on the control arm but still not sure about that. There is only about 1/8" gap between the endlink and control arm. I was wondering if anyone could see about there endlinks gap with the control arm.

One last thing. I wanted to thank Davaro for his reply of great wisdom.

the suspension noise could be strut mounts
