    timed both with the tdc-#1 and near as I can see the timing mark on balancer--set and reset both cams--engine starts fine and compression is equal on all cyl... still have low vac and lope or pulsation at idle and low accelation

  • misguided Oct 09, 2008

    should have posted that I found the correct solution on my own. My reapir manual does'nt indicate that there are adjustments on both cams, so when I startec the engine it was out of time.

    runs like the day I bought it. thanks for the input

Did you do the engine TIMING as per the manufacturer ?
Replacing timing belt does not assure exact TIMING as specified

Loping idle 1995 honda accord occurs when ac is on for a few minutes seems like the compressor clutch is engaging and disengaging it is a nuisance and the air doesnt blow as cold


bad compressor? (seizing) or
or engine is so weak, at idle (lean), that it cant run your compressor.
the reason for the lope is the ECU idle speed controls going crazy.
id say, the ISC is a victim here.

96 concord 3.5 lopes at idle and bucks at a constant speed


What you describe is a cylinder not contributing,This can be from a misfire such as a broken sparkplug wire to a broken sparkplug, If it was a vacuum leak it would lope at idle but not buck at high speed,

Rough idling/loping at idle it otherwise runs fine off idle.


1. Vacuum leakage Check throttle body and intake manifold for tightness. check all vacuum hoses.
2. Faulty fuel or pump or electrical.
3. Plugged PVC valve.
4. Air filter clogged
5. Leaking head gasket.
6. Camshaft lobs worn.
All of these porblems can cause lopes or erratic idle.

I have a 98 dodge stratus. timing belt broke, was replaced. the engine runs perfect at RPMs higher than idle, but at idle whole engine and car shake. . . . why???


This car has a very possible chance of having either a slightly bent valve, causing the loping idle, or the belt was installed a tooth off on the timing, it's one of the two.easiest way to deduce this would be to recheck the timing belt marks, to certify they're correct, then to do a simple compression check, get back to me with any questions, I'M HERE TO HELP!!!

Loping idle with a '98 Subauru 2.5


This usually happens when the fuel pump is loosing pressure.

I will just advice you make a replacement on the fuel pump. It is located in the fuel tank beneath the back seat.

Be sure to consider the rating on the fuel pump when replacing.

Good luck and rate my solution.
