I have a 1990 isuzu trooper that had a loose exhaust pipe.

Customer Question
I have a 1990...

I have a 1990 isuzu trooper that had a loose exhaust pipe. it ran loud. then after a few weeks, it started idling up then down in neutral. now, I've secured the pipe, no noise or leak, and it starts but won't idle. it ran the highway, but if i idle, it dies. also, the starts have been sluggish just before I secured the pipe.

Mechanic's Assistant: Have you checked the battery, particularly the terminal connections? Are they corroded?

Slightly,

Mechanic's Assistant: Are you fixing your Trooper yourself? What have you tried so far?

The bolts were loose to the exhaust pipe leading to engine. I tihgtened them, and replaced the gasket

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Don't think so

HI,

I am sorry that you have not been helped yet. I just came online and saw your question.

I need to know if it is the 2.6 or 2.8l engine

Is the check engine light on

Based upon the symptoms, I suspect either air intake leak, tp sensor or iac valve, but I need the above information to check a few things first

Hi Eric, Thanks for replying. It's the 2.6 four banger

I thought it might be the air flow meter, so i detached to see if I could run without... it did, but not very far :) so I re-attached and again, once I let it go to idle, it just barely hangs on below 1rpm then kaput. one thing i should mention is, it had trouble turning over each start for about three weeks leading up to this. and, after it ran for a while then shut off, the turn over was even slower, as if the battery didn't have enough time to recharge.

have no idea if above is related to idle-die issue... so when i had foot on gas, and running, it's like it's skippy, like the engine was sort of firing, but not all the way, then it would fire seemingly normal for like a block, or when going faster. anyway, prolly too much info here. lmk what you think
Auto Mechanic: Eric, Automotive Repair Shop Manager replied 11 months ago

HI,

Ok, have you checked the fuel pressure yet. If not, we need to start with that

No vacuum to regulator ............................. 294 kPa (42 psi) at idle
With vacuum to regulator ........................... 245 kPa (35 psi) at idle

i'll have them check... i also wonder since i ran it with a loose exhaust pipe (close to engine) if I hurt the egr valve, or flamed the exhaust valves (or maybe intakes?)...
Auto Mechanic: Eric, Automotive Repair Shop Manager replied 11 months ago

HI,

Possible that the exhaust valves are burnt, but I would expect to see the check engine light on due to severe misfire code they should set. You can have a compression leakdown test performed which will tell you that.

For the egr valve, remove the vacuum hose and see if it idles. Will likely be high idle, but if it doesnt die out, then the diaphram is shot on the egr valve.
