Engine loose power

check timing and compression - how many miles?

Aribarabara,

Don't check the timing as stated or touch the distributor. The timing is controlled, altered, modified, and adjusted by the PCM (aka computer). Describe in detail what you mean buy a loss of power. Also are here any performance r drivability issues associated with the loss of power?

POST THE RESULTS OF THE FOLLOWING TESTS !!!!!

Fuel pressure and volume
Engine vacuum pressure
Exhaust back-pressure
Cylinder leak down

ase - if it jumped time it would loose power wouldn't it??? if the compression is low it would loose power as well.

Jerry,

Under normal circumstances what you say would be true. By normal circumstances I mean a normal individual. Normal individual is a reference to the original poster. (I KNOW ENGINES). You’ll see that the original poster makes no reference to a US or non US engine in his vehicle. Furthermore in either case (US or non US) both engines use a timing chain and not a belt. The chains in these engines (DO NOT) stretch or break. Typical chain life is (AT LEAST) 300 thousand miles, so untill something changes a (JUMPED TIME) issue can be ruled out. I’ll give you a compression issue, but with that being said that's why I asked to see the results of a cylinder leak down test. On the other hand there is always the possibility that the poster is a lunatic who is testing me or us. If that’s the case his sorry ass is in for a big surprise.
